Java Program That Tells Whether A Student Hass Passed Or Failed
Oct 21, 2014
A University offers a course that prepares students for the county licensing exam for real estate brokers. Last year, twenty students who completed this course took the exam. The university wants to know how well its students did an exam. You have been asked to write a program to summarize the results. You have been given a list of these 20 students. Next to each is written a1 if the student passed the exam or a2 if the student failed the exam.Your program should analyze the results as follows:
i.Input each test result (i.e., a1 or a2). Display the message Enter result on the screen each time the program requests another test result.
ii.Count the number of test results of each type.
iii.Display a summary of the test results, indicating the number of students who passed and the number who failed.
iv.If more than 15 students passed the exam, output message, Bonus to the instructor
Ok, so I have to make a program that tells the user to type a sentence and at the end of the sentence a "." must be put to end the program. If a "." period is not entered, it must re-prompt the user to enter a period. On top of all this, the program has to count the number of letters in the sentence. I cant seem to get the while loop working and I cant find anywhere how to make a counter count the number of letters.
import java.io.*; class Sentence //The purpose of this program is to
I want to write a java program which displays to get the GPA of a student as a keyboard input. Then display the class of the degree according to the following criteria using a switch-case statement (if-else statements cannot be used). If the user insert an invalid gpa you should display a message Invalid GPA.
gpa ≥ 3.50 First Class Hons 3.49 ≥ gpa ≥ 3.00 Upper Second Class Hons 2.99 ≥ gpa ≥ 2.50 Lower Second Class Hons 2.49 ≥ gpa ≥ 2.00 Pass 2.00 ≥ gpa Fail
Here is my code:
import java.io.*; public class q7 { public static void main(String[] args) { InputStreamReader ISR=new InputStreamReader(System.in); BufferedReader BR=new BufferedReader(ISR);
[code]...
.But when I use Command console to run this it says: 1111.jpg. I also wanna know is there another way to do this with switch- case statements.
And in the server log there is a long list of comments, the first which looks to be of significance to this issue is:
WARNING [http-apr-8080-exec-57] org.apache.catalina.deploy.NamingResourcesImpl.cle anUp Failed to retrieve JNDI naming context for container [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/transBoard]] so no cleanup was performed for that container javax.naming.NameNotFoundException: Name [comp/env] is not bound in this Context.

There are others further down the list which might also be significant such as:

The corresponding line of code for the first warning that I listed is for the DataSource object and I wrote it as follows:

the issue has something to do with connecting to the database since it ran fine before I added the database related code.

I just have not got the chance to spend much time on it lately I know a bit but I'm not an expert or even intermediate with Java so I'm trying to make a program where the teacher enters the grade of each student and its stored in a variable the only problem is if I use a for loop the variable in which the result will be stired will be overwrite by the last repetition of the loop,I think the idea would be a nested loop but how I would go about using it in this situation,
here is my java code.
import java.util.Scanner; class maths{ public static void main(String[] args)
I have written a program student record system but can not save data to view or submit record. Able to run the program but failed to submit record or view pre-submitted records.
What's up with this. Just trying to test my hands on java packages, and had this error(by java) after successful compilation:

i found that jstl1.1 jar didn't have the above mentioned class.I replaced jstl1.1 with jstl1.2 jar.i verified that jstl1.2 jar had JstlCoreTLV calss.but even after this replacement of jar i am facing the same issue.
I don't get an in code error but when I run this one it crashes at the print line "failed conversion error". I've used this style format in another program and format worked ok, what doesn't it like

My code compiles successfully, but when executing I never get an output, and then the message: ">Process failed to respond; forcing abrupt termination...". Is there an infinite loop in my ab method, is that why?
public class Test{ boolean ab(String s){ boolean seenAnA=false; while(true){ if(s.charAt(0)=='a'){ seenAnA=true; s=s.substring(1);
There are few modules in our application whose performance degrade with time when 50-100 simultaneous users are working on them at a given instance.The memory allocations are taken care of to allow maximum data.My issue to where to start finding the root cause.
I am currenlty using JvisualVM for profiling and finding memory leaks..Do i need to Simualte 50-100 virtual users and start finding the memory leaks with JvisualVM or working with a single user would do ?
Create an abstract class called Student. The Student class includes a name and a Boolean value representing full-time status. Include an abstract method to determine the tuition, with full-time students paying a flat fee of $2,000 and part-time students paying $200 per credit hour. Create two subclasses called FullTime and PartTime. Create an application that demonstrates how to create objects of both subclasses."
public abstract class Student { private String name; private int credits; public Student(String name){ this.name = name; credits =0;
Below mentioned table which show data on WEB page, thereof i need to develop page for my practice, steps to develop this like as following.
1.Tool Required to develop 2.Connectivity JDBC
create table student (ROLLNO NUMBER, NAME VARCHAR2(20), DOB DATE, REG_DATE DATE, ADDRESS VARCHAR2(100), PIC LONG )
INSERT INTO STUDENT VALUES(1,'ALI',TO_DATE('01-JAN-1982'),SYSDATE,'',''); INSERT INTO STUDENT VALUES(2,'JHON',TO_DATE('01-JAN-1985'),SYSDATE,'',''); INSERT INTO STUDENT VALUES(3,'CHARLI',TO_DATE('01-JAN-1990'),SYSDATE,'','');
For my lab this week I have to print out four arrays. The arrays have to be 5 units long. The first three arrays are the student's exam grades for exam 1, 2 & 3 and the fourth array should be the average for each student's three tests. The program should ask the user to input the grades in and then the program should compute the average. For example the program should print this if these are the exam grades the user imputs:
Exam 1 Exam 2 Exam 3 Average 65 79 80 74.66 79 82 59 73.33 99 100 98 99 and so on.......
I thought I wrote the program perfectly and when I compile it there are no errors but when I run it, it only lets me input the numbers for the first three students and then prints out something so strange.
here is my program:
public class Lab9{ public static void main(String[] args){ java.util.Scanner input = new java.util.Scanner(System.in); int i, sum; double avg; sum = 0; int A[ ] = new int [5]; int B[ ] = new int [5]; int C[ ] = new int [5]; double avg1[ ] = new double[5];
I'm writing a Java program to get the gpa of a student as a command line argument. Then display the class of the degree according to some criteria. Here is my code. But it says "ArrayIndexOutOfBoundsException :0". How can I fix this?
public class Stgpa { public static void main(String[] args) { double gpa= Double.parseDouble(args[0]); if(gpa>=3.6) System.out.println("Class of the degree is: First Class Hons"); else if(3.6>gpa && gpa>=3.4)
prompts user for the grades of each of the students and saves them an int array called grades. Your program shall check that the grade is between 0 and 100. program should then check if the grade is equal to or greater than 50, where 50 is the pass rate.
A sample output :
Enter the number of students: 3 Enter the grade for student 1: 55 Enter the grade for student 2: 108
Invalid grade, try again...
Enter the grade for student 2: 56 Enter the grade for student 3: 57
The average is 56.0 The maximum is 57 The minimum grade is 55 The number of fails is 0 The number of passes is 3 ..
I have to read in a file that that has Student, Employee, Faculty....such as name, last name, salary...etc
Example of a file input Java Code: Student, John, Doe, [email]johnDoe[At]yahoo.com[/email], 123,Wonderland Ave, 21323,TX PhoneNumber,Cell,111,222,3333 Student, Jesus,Satan,[email]jesus[At]satan.com[/email,666, HeavenHell Dr., 666666,CA PhoneNumber,Work,111,333,5555 mh_sh_highlight_all('java'); Java Code: while(input.hasNext()){
[code]...
There is more code, but it's repetitive. Now, I keep getting an error. Array of bounds. I believe i get the error because the phone number. The phone number is on the next line..I created a different arraylist for phonenumber, but I dont know how to match it with the correct person, student, employee...etc.
Write a program that promts a professor to input grades for five different courses for 10 students. Prompt the professor to enter only A,B,C,D, or F for grades(A is the highest grade, F fail). use variables for student number(1 through 10) and grade numbers(1 through 5). create a menu for Search. if the user select search it will prompt a letter correspond to grade. display all student with selected grade. if the user just enter nothing, display all student with their grade sorted from highest to lowest.
I had to make a program that allowed the user to enter the number of students and the students names and grades and then print out the name with the grade in descending order. right now I only have it where it prints the names out in descending order. how do I get it the print out with the grade?
Here is my code
import java.util.*; public class Grades { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("Enter the number of students: "); int numofstudents = input.nextInt();
