Helo,

I need to divide Integer value by 2. Is it only one method to create
new Integer? Looks cumbersome.

Integer i = new Integer(10);
....
Integer i = New Integer(i.intValue()/2);

Thank You

Yes, like the documentation says, Integer (and all the primitive
wrapper classes) objects are immutable.  However, if you're using Java
5 or later, you don't need to write out the unpacking to an int and
creation of new Integers yourself: the language will automatically
unbox and box primitives into their respective wrappers.

You could write the above as

Integer i =3D 10;
Integer j =3D i / 2;

and let Java worry about the rest.  Alternately, you could use int
instead of Integer.

You can also write the OP's expression as
   Integer i = 10;
   i = i / 2;
Which the OP should find is not as "cumbersome".

My guess is that you should use:

int i = 10;
i = i / 2;

and wrap in Integer when you need it.

You can use primitive ints or let autoboxing simplify the code.
