Answer: option B) Variable Shadowing

Variable Shadowing: If the local variable and instance variable have same name The value of the local variable will be printed(shadowing the instance variable), whenever you print (access) it in the method.

Example:

In the following Java example, the class ShadowTest has a method (show()). and two instance variables (name, age).

In the show() method there are two variables same as the instance variables (name and age).

When you invoke print (access) them in the method, the local variable values will be printed shadowing the instance ones.

public class ShadowTest
{  
   String name = "Saru";
   int age = 28;
   public void show()
   {
      String name = "Varu";
      int age = 21;
      System.out.println("Name: "+name);
      System.out.println("age: "+age);
   }
   public static void main(String args[])
   {
      new ShadowTest().show();
   }
}
