example given
String str2 = "Hello world!";
Surely this statement is not correct as
Integer intInstance3 = 5;
is creating an instance of the Integer class without using new keyword
Good question. What happens above is called boxing and unboxing
feature (introduced from Java SE 5), in which the compiler adds code
below for you
Integer intInstance3 = new Integer(5);
