Taking Advantage of Immutable Objects in Java

Taking Advantage of Immutable Objects in Java

zero = new Integer(0);return Boolean.valueOf("true");

Integer and Boolean are immutable; so, it is a bad idea to create objects that represent the same value, those classes have built-in caches for frequently used instances. So, the programmer can take advantage of this:

zero = Integer.valueOf(0);return Boolean.TRUE;
