public static void main(String[] args) {

String a ="bla";
String b = "bla";

Integer c = new Integer(10);
Integer d = new Integer(10);

Integer e = 10;
Integer f = 10;

System.out.println("Strings :" + (a==b));
System.out.println("Integers :" + (c==d));
System.out.println("Integers autobox :" + (e==f));


}

}

This prints
Strings :true
Integers :false
Integers autobox :true

What I didn't expect is that when I used autoboxing, the references are the same... Aren't there 2 different Integer objects made ??
Can someone explain please ? Thanks.
