In Java, if there is a local variable in a method with same name as instance variable, then the local variable hides the instance variable. If we want to reflect the change made over to the instance variable, this can be achieved with the help of this reference.

class Test 
{ 
    // Instance variable or member variable 
    private int value = 10;  
  
    void method() 
    { 
        // This local variable hides instance variable 
        int value = 40; 
  
        System.out.println("Value of Instance variable :"
                            + this.value); 
        System.out.println("Value of Local variable :"
                            + value); 
    } 
} 
  
class UseTest 
{ 
    public static void main(String args[]) 
    { 
        Test obj1 = new Test(); 
        obj1.method(); 
    } 
} 

Output:

Value of Instance variable :10
Value of Local variable :40
