public class T1 {
public static void main(String[] args) {
// TODO Auto-generated method stub
Integer i1 = 1000;
Integer i2 = 1000;
if(i1 != i2) System.out.println("different objects");
if(i1.equals(i2)) System.out.println("meaningfully equal");
}
}
O/P for this is:
different objects
meaningfully equal
Where as
public class T2 {
public static void main(String[] args) {
Integer i3 = 10;
Integer i4 = 10;
if(i3!=i4)System.out.println("Crap dude!!");
if(i3 == i4) System.out.println("same object");
if(i3.equals(i4)) System.out.println("meaningfully equal");
}
}
Produces Following O/P:
same object
meaningfully equal
I didn't understand why in class T2 if(i3!=i4) didn't get triggered I'm refering SCJP 1.6 but not able to understand.
Please help me.
