Question

public boolean isRight() {
    if(xposition == ( (oposition-1) && (oposition != (12 && 8 && 4))) {
        return true;
    } else {
       return false;
    }
}

“xposition” and “oposition” are assigned values during the runtime of a program.

The error is in (12 && 8 && 4) I need to make sure that the value of “oposition” is not equal to 12 and 8 and 4.

I don’t know what is wrong here. Please help

Maybe right logic is:

if(xposition == ( (oposition-1) && (oposition != 12 && oposition != 8 && oposition != 4) ) )

If you have a lot of numbers:

int[] numbers = { 
    12, 8, 4, 13, 2, 7
};
boolean validation = true;
for (int i : numbers) {
    if (oposition == i) {
        validation = false;
        break;
    }
}
