iii. What is wrong with the following while statement?

D. Explain two (2) programming situations that will require the use of overloaded methods [5 marks]

Answer 1

1 There is no closing curly brace.

while (c <= 5) {
    product *= c;
    ++c;
}

2 Semicolon after else.

if (gender == 1)
    System.out.println("Woman");
else
    System.out.println("Man");

3 If z is greater than or equal to 0, then the loop will become infinite.

while (z >= 0) {
    sum += z;
    z--;
}

D If you want the child method to have different behavior, when you need to implement an abstract method or an interface method.
