You can write a program which empirically determine how many values are cached. BTW: Byte, Short, Integer and Long are all -128 to 127 but for Character its 0 to 127.

I writing code like this:

User u = new User() {

private String login = “teste2″;

@Override
public String createHashValidate() {
this.setLogin(login);
return super.createHashValidate();
}
};

System.out.println(u.createHashValidate());
