Question
class Calculator { public static int add(int a, int b) { return a + b; } public static int add(int a, int b, int c) { return a + b + c; }}public class Main { public static void main(String[] args) { int result1 = Calculator.add(10, 20); int result2 = Calculator.add(10, 20, 30); System.out.println("Result1: " + result1 + ", Result2: " + result2); }}a.Result1: 30, Result2: 60b.Result1: 20, Result2: 30c.None of the aboved.Compilation Error
Solution
The correct answer is a. Result1: 30, Result2: 60.
This is because in the Main class, the add method of the Calculator class is called twice. The first time, it's called with two arguments (10 and 20), which triggers the first add method in the Calculator class (which adds two integers together). The result (30) is stored in result1.
The second time, the add method is called with three arguments (10, 20, and 30), which triggers the second add method in the Calculator class (which adds three integers together). The result (60) is stored in result2.
Finally, the results are printed out, so the output of the program would be "Result1: 30, Result2: 60".
