    Default Variable error help

    Hello,
    My assignment is to write code simulating dice, generating 10000random numbers between 1-6. Then I have to display the number of 1's that appeared, the number of 2's that appeared, etc in a joptionpane like this:

    The number of 1s appeared is
    The number of 2s appeared is
    The number of 3s appeared is
    The number of 4s appeared is
    The number of 5s appeared is
    The number of 6s appeared is

    This is my code so far:
    public class ARG
    {
    		public static void main(String[] args)
    		{
     
     
    			  int[] A = new int[10000];
     
    			for(int i=0; i<A.length; i++)
    				A[i] = 1 + (int) (6*Math.random());
             }
             {
             for(int i=0; i<A.length; i++)
    			System.out.println(A[i]);
     
     
    		for(int i = 0; i < 6; i++)
       		System.out.println("Total number of " + (i+1) + " = " + A[i]);
     
    		}
     
    }

    The variable errors I keep getting are:
    F:\ARG.java:13: error: cannot find symbol
    for(int i=0; i<A.length; i++)
    ^
    symbol: variable A
    location: class ARG
    F:\ARG.java:14: error: cannot find symbol
    System.out.println(A[i]);
    ^
    symbol: variable A
    location: class ARG
    F:\ARG.java:18: error: cannot find symbol
    System.out.println("Total number of " + (i+1) + " = " + A[i]);
    ^
    symbol: variable A
    location: class ARG
    3 errors

    Tool completed with exit code 1

    I'm a beginner so please if you can help me in any way, it would be appreciated.

    Check that the {}s are properly paired.
    I can't tell in the code that you posted because the vertical alignment of statements doesn't follow standards.
    The statement with the beginning { should start directly above the ending }
    Your {}s waver left and right and make it hard to see what code belongs where.

    Comment {} on line 11, then it would be like this

    public class ARG
    {
    public static void main(String[] args)
    {


    int[] A = new int[10000];

    for(int i=0; i<A.length; i++)
    A[i] = 1 + (int) (6*Math.random());
    //}
    //{
    for(int i=0; i<A.length; i++)
    System.out.println(A[i]);


    for(int i = 0; i < 6; i++)
    System.out.println("Total number of " + (i+1) + " = " + A[i]);

    }

    }

    You actually closed your main method and class bracket before your for loop, so the computer never understands what is your for loop for, change your bracket and it should take out those errors it's showing to you now

    Hope this helps
