//Java code for using 'this' keyword to 
//refer current class instance variables 

//code taken from www.geeksforgeeks.org but has been edited

class Test 
{ 
    int a; 
    int b; 
      
    // Parameterized constructor 
    Test(int a, int b) 
    { 
        //this helps differentiate between members of class and parameters
        this.a = a; 
        this.b = b; 
    }
