Analyze the following code. public class Test { public static void main(String[] args) { System.out.println(max(1, 2)); } public static double max(int num1, double num2) { System.out.println("max(int, double) is invoked"); if (num1 > num2) return num1; else return num2; } public static double max(double num1, int num2) { System.out.println("max(double, int) is invoked"); if (num1 > num2) return num1; else return num2; } }

  1. The program cannot compile because you cannot have the print statement in a non-void method

  2. The program cannot compile because the compiler cannot determine which max method should be invoked

  3. The program runs and prints 2 followed by "max(int, double)" is invoked.

  4. The program runs and prints 2 followed by "max(double, int)" is invoked.
