Which of the following will throw an error? A. int method(int a, int b) int method(int num) B. float method(int a, float b) float method(float var1, int var2) code example

Example 1: method overloading

//https://www.geeksforgeeks.org/overloading-in-java/
// Java program to demonstrate working of method
// overloading in Java. 
  
public class Sum { 
  
    // Overloaded sum(). This sum takes two int parameters 
    public int sum(int x, int y) 
    { 
        return (x + y); 
    } 
  
    // Overloaded sum(). This sum takes three int parameters 
    public int sum(int x, int y, int z) 
    { 
        return (x + y + z); 
    } 
  
    // Overloaded sum(). This sum takes two double parameters 
    public double sum(double x, double y) 
    { 
        return (x + y); 
    } 
  
    // Driver code 
    public static void main(String args[]) 
    { 
        Sum s = new Sum(); 
        System.out.println(s.sum(10, 20)); 
        System.out.println(s.sum(10, 20, 30)); 
        System.out.println(s.sum(10.5, 20.5)); 
    } 
}

Example 2: method overloading

Method overloading is providing two separate methods in a class 
with the same name but different arguments, while the method return type 
may or may not be different, which allows us to reuse the same method name.
