Examine the code below, then do the following:. 1. Test it and determine whether it works as expected. 2. Write the loop with a boolean condition (not simply true.) 3. Write the loop and without using a break. int possum = 0, negsum = 0, num = 0; Scanner scanner = new Scanner(System.in); while(true) { System.out.println("Enter a number: "); num = scanner.nextInt(); if (num 0) possum += num; else break; System.out.println("possum = " + possum + " and negsum = " + negsum)
