INTRODUCTUION:
Two key ideas of object-oriented programming—overloading and overriding—are frequently applied in Java programming. These two ideas are used to give the same class various methods and functions.
TECHNIQUES:
Java’s overloading feature allows you to designate numerous methods with the same name but distinct inputs. The compiler chooses which method to use based on the arguments provided to it, allowing you to use the same method name for different operations. Method overloading is used to provide the same method name many capabilities and to make the code more readable. In method overloading, the method name and the number of parameters should both be varied, as should the method signature.
For example:
public class OverloadingExample {
public void add(int a, int b){
System.out.println(a+b);
}
public void add(int a, int b, int c){
System.out.println(a+b+c);
}
}
In the aforementioned example, two methods with the same name, “add,” but distinct parameters, have been defined. Both the first and second methods take two and three integer parameters, respectively.
OVERRIDING:
Java allows you to construct a method in the subclass that shares the same name, return type, and parameters as a method in the superclass by using the overriding technique. A method is considered to be overridden when it shares the same signature as a method in the superclass. A method that is already defined in the superclass might be provided with a different implementation using method overriding. To implement runtime polymorphism, it is employed.]
For example:
public class Animal {
public void animalSound() {
System.out.println(“The animal makes a sound”);
}
}
public class Cat extends Animal {
public void animalSound() {
System.out.println(“The cat meows”);
}
}
Two classes, Animal and Cat, are defined in the example above. The animalSound() method is overridden by the Cat class, which extends the Animal class. The overridden method in the Cat class will be called when we use the animalSound() function using an object of the Cat class, and it will print “The cat meows” to the console.
CONCLUSION:
In conclusion, the principles of overloading and overriding are crucial to Java programming. While overriding is used to offer a new implementation of a method that is already defined in the superclass, overloading is used to create numerous methods with the same name but different parameters. Both of these ideas are essential to the implementation of polymorphism, an essential idea in object-oriented programming.
