Question

I can’t seem to find a way to fix this problem. All I’m doing is declaring an integer and the compiler is telling me that the code is unreachable.

class MyStack {

    Object[] myStack = new Object[50];

    private void push(Object obj) {
        int count = 50;
        while (count > 0) {
            myStack[count] = myStack[count - 1];
            count--;
        }
        myStack[0] = obj;
    }

    private Object pop() {
        return myStack[0];
        int count2 = 0; // Unreachable code
    }
}

Once you return from a method, you return to the method that called the method in the first place. Any statements you place after a return would be meaningless, as that is code that you can’t reach without seriously violating the program counter (may not be possible in Java).
