Have been asked to remove return statements from my loop and it is difficult to do that and still get the same output i want.

int[] a = getFreePositionToFit(product);
       if (a == null ) {
           return false;
       }
       if (maxWeight < product[Data.WT]) {
           return false;
       }
       for (int i = a[0]; i < a[0] + product[Data.WID]; i++) {
           for (int j = a[1]; j < a[1] + product[Data.LEN]; j++) {
               BOX[i][j] = product[Data.ID];
           }
       }
       maxWeight -= product[Data.WT];
       return true;
   }

What I have tried:

i have tried to declare a boolean variable and use that.

Boolean result= true;

Solution 1

You are right to use a boolean variable, next is to use if else if, e.g.

boolean result = true;
if (condition 1) {
  result = false;
} else if (condition 2) {
  result =  false;
} else { // none of the above
  // do something
}
return result;

You can also combine conditions 1 and 2 with a || operator.
