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();
[Code] .....

i am running into a problem with my program. It seems my BasicCalc class is running fine but having some difficulties with displaying it with a system.out. println instead of the system.out.printf. When i do try and change it i get this result:
C:myJava>javac BasicCalc.java
C:myJava>javac Calculate.java
Calculate.java:42: error: no suitable method found for println(String,double,char,double,double)
System.out.println("%f %s %f = %f", value1, op, value2, answer);

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;

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)
[Code].....

I want to create a Student class that is able to search, borrow, return, and reserve books. This is what I have done so far:
public class Student
{
private String username;
[Code].....
I think that I might need an array where to remember all of the books that the student has borrowed, but I'm not sure how to do that as well.

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];
[code]....

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 am quiet stuck on this one.

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

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.
