java array printing the repeated numbers , array in the array [closed]

Question

Please could you tell me how its work in section (g[ss[i]]++;) and tell me the sequence of output in java

class A{
    public static void main(String []a){
        int []ss={1,2,3,4,2,3,3,1,1,1,5,6,4,5,4};
        int []g=new int[15];
        for(int i=0;i<15;i++){
            g[ss[i]]++;
        }
        for(int i=1;i<15;i++){
            System.out.println(ss[i-1]+"=="+g[i]);
        }

    }
}

Answer 1

Can't you run it?

g[ss[i]]++; can be rewritten as

int index = ss[i];
g[index] = g[index] + 1;

So it's counted number of each number in ss.

It's very error prone, and you should never do something like that.

Answer 2

Just run it?

1==4
2==2
3==3
4==3
2==2
3==1
3==0
1==0
1==0
1==0
5==0
6==0
4==0
5==0

This should be your output.
