This program is to grade exams, now i need to add the correct answers and them loop back to grade another exam. Need help I;n stuck.

 import java.util.*; 
 
public class Grades
{
public static void main(String[] args)
{
 
Scanner keyboard = new Scanner(System.in);
 
System.out.println("How many question are in the quiz?");
int num = keyboard.nextInt(); 
keyboard.nextLine();
 
String[] Grades = new String [num];
String[] Student = new String [num];
 
for (int count = 0; count < Grades.length; count++)
{
System.out.println("Please enter key of the quiz(please upper case) " + count );
Grades[count] = keyboard.nextLine(); 
}
 
System.out.println(); 
for (int st = 0; st < Student.length; st++)
{
System.out.println("Please enter the student answers " + st );
Student[st] = keyboard.nextLine(); 
}
 
System.out.println("quiz key\tstudent answer\tpoints.");
for (int a=0; a<Student.length;++a){
 
 
if (Grades[a].equals(Student[a])) {
System.out.print(" " + Grades[a] +"\t\t "+ Student [a]+ "\t\t " + 1 );
System.out.println();
 
}
else { 
System.out.print(" " + Grades[a]+ "\t\t "+ Student [a]+"\t\t" + 0); 
System.out.println();
 
}
} 
}
}

Now that I've added the code tags which you had forgotten can you explain what it is you say you are stuck with again because I didn't get your explanation.

hi, this code is to grade exams, with two arrays, one for the key and one for the student answers, then the program have to comparre the studen answers with the key, to grade the test. I got the two arrays to get the input, and storage the data. Now I need a code to grade the test for the student, add the correct answers. Them I need to loop to grade another test. Thanks for any help.

If I got your question well then what you need is a counter

 int correct = 0; 
if (Grades[a].equals(Student[a])) {
System.out.print(" " + Grades[a] +"\t\t "+ Student [a]+ "\t\t " + 1 );
System.out.println();
correct++;
}
else { 
System.out.print(" " + Grades[a]+ "\t\t "+ Student [a]+"\t\t" + 0); 
System.out.println();
 
}
 
 

Now you have the count for the correct ones in the variable correct.

Thank you for the help.
