Why it is not equal?

Question

Integer i = new Integer (42);
Long l = new Long (42);
if(i.equals(1))
     System.out.println("Equal");
else
      System.out.println("NOT Equal");Why it is Not Equal?can you explain me?

Answer 1

When you do
i.equals(l) - equals method of the Integer class will be called.
and equals method in Integer class is like dis
public boolean equals(Object obj) {
     if (obj instanceof Integer) {
     //compare the two objects and return the result
     return false;
The two objects will be compared only if both of them are Integer types, other wise it will simply return false.
