equals method

[Smitha Ballikar]

  public class Sample{
 
Object ob = new Object();
 
void compareOb(){
 
 if(null.equals(ob)) 
    System.out.println("We are Equal");
 
  else 
    System.out.println("We are not Equal");
}
 
 public static void main(String [] args){
    Sample s =new Sample();
    s.compareOb();
 
 }
 
}

Here it gives compiler error.I thought it would print "We are not Equal".
Cant we use null with equals method??

[Rushikesh Wagh]

.equals() Method Is Used To Compare The Objects And null Is Not An Object. Hence It Has Compile Time Error. Please Do Correct Me If I m Wrong.

Rushikesh is correct, null is a literal, not an object. Trying to call a method on null would be like trying to call a method on the number 5 or the boolean value true.

on the same lines, try this :

Byte b2 = new Byte("11");

if(b2.toString() == b2.toString())
System.out.println("True");
else
System.out.println("False");
