Usage of the this and super keywords

The this keyword provides a reference to the current object. The super keyword refers to the parent class object. These keywords allow us to refer to a variable or method that has the same name in the current context and in the parent object.

Usage of the this keyword

Here is the most popular example:

class A {
    private int count;
    public void setCount(int count) {
        count = count;         // 1
    }
    public int getCount(){
        return count;          // 2
    }
}

The first line looks ambiguous, but, in fact, it is not: the local variable, int count , hides the private property instance int count. We can demonstrate this by running the following code:

A a = new A();
a.setCount...
