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.
In my framework==
I use implicit wait in Selenium. Implicit wait
is an example of overloading. In Implicit wait
we use different time stamps such as SECONDS, MINUTES, HOURS etc.,
A class having multiple methods with
same name but different parameters
is called Method Overloading
public class Multi{ //Super class
public void multi(String name){ //String parameter
………………
}
}
Public class Multiplication extends Multi(){
Public void multi(){//No Parameter
………..
}
Public void multi(int x){ //integer parameter
}
Public static void main(String args[]){
Multiplication multiplication = new Multiplication();
multiplication.multi();
}
}
static int plusMethodInt(int x, int y) {
return x + y;
}
static double plusMethodDouble(double x, double y) {
return x + y;
}
public static void main(String[] args) {
int myNum1 = plusMethodInt(8, 5);
double myNum2 = plusMethodDouble(4.3, 6.26);
System.out.println("int: " + myNum1);
System.out.println("double: " + myNum2);
}
// 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));
}

perator overloading is the ability to redefine the functionality of the operators. Programming languages like c++ supports operator overloading
