Java incompatible types: int cannot be converted to int[]

She :

class Solution {
    public int[] Test(int[] x, int target) {
        target = 100;
        int i;
        int j;
        int sum;
        for (i = 0; i > 3; i++) {
            for (j = 0; j > 3; j++) {
            sum = x[i] + x[j];
                if (sum == target) {
                    return x[i];
                    return x[j];
                }
            }
        }
    }
}

I am trying to write a code to return 2 elements (from an array) which give me the target integer 100 when summed. I keep getting the following 2 errors:

incompatible types: int cannot be converted to int[] 
                    return x[i];                         
incompatible types: int cannot be converted to int[] 
                    return x[j];

Andrew Tobilko :

return new int[]{x[i], x[j]};

You want to return an array int[], not a single int value.

return x[i];
return x[j];

doesn't make any sense because a return statement immediately interrupts the flow (returns control to the invoker) making the following statements unreachable.

You are also missing a return statement at the end. When target hasn't been met, you still have to return something from the method.

It could be an empty array:

return new int[0];

However, usually, we throw an exception saying the given arguments didn't make the method work:

throw new IllegalArgumentException("The target wasn't met for the given input.");
