Question

The reference to an object that is passed to any object's nonstatic class method is called the ____.1. this reference2. magic number3. literal constant4. reference

Answer 1

Answer:

The correct answer for the following question is this reference.

Explanation:

this reference is used for pointing the current object or parameter.

Following is the exemple of this reference in java language -

class test // class

{

int x,y; // data member

test(int x, int y) // constructor

{

this.a = x; // pointing the object

this.b = y; // pointing the object

}

public static void main(String args[]) // main method

{

test ob = new test(10, 20); // passing value and create instance

ob.display(); // calling function

}

}

• By using the this object we can passed to any object of the non-static class method.
• Magic number, literal constant and reference are not used for pointing the reference of an object.
