Overriding in java

Overriding is a feature that allows a subclass or child class to provide a specific implementation of a method that is already provided by one of its super-classes or parent classes.

java override example

class Parent {
    // private methods are not overridden
    private void m1()
    {
        System.out.println("In parent m1()");
    }
  
    protected void m2()
    {
        System.out.println("In parent m2()");
    }
}
  
class Child extends Parent {
    // new m1() method
    private void m1()
    {
        System.out.println("In child m1()");
    }
  
    // overriding the protected method
    
    @Override
    public void m2()
    {
        System.out.println("In child m2()");
    }
}
  
class Main {
    public static void main(String[] args)
    {
        Parent obj1 = new Parent();
        obj1.m2();
        Parent obj2 = new Child();
        obj2.m2(); // call the object's method of child
    }
}

output:

In parent m2()
In child m2()
