Computer Science on instances of the Car and Motorcycle classes, the overridden methods unique
to each subclass are executed. This showcases the concept of method overriding,
which is a form of run-time polymorphism.

Method overloading
FOR ONLINE READING ONLY
Method overloading permits several methods to share the same name while
possessing distinct parameter lists. It offers a means to define methods that execute
similar tasks but with varying input types or counts of parameters. The compiler
selects the appropriate method for invocation based on the arguments supplied to it.
Program Example 5.38 illustrates the concept.

Program Example 5.38:
Java program to demonstrate method overloading

public class ArithmeticOperations {

// Method to add two integers
public int add(int a, int b) {
return a + b;
}

// Method to add three integers
public int add(int a, int b, int c) {
return a + b + c;
}
// Method to add two doubles

public double add(double a, double b) {
return a + b;
}

// Method to concatenate two strings
public String add(String a, String b) {
return a + b;
}
// Method to multiply two integers

public int multiply(int a, int b) {
return a * b;
}
