Message:

use of "final" in variable declaration

Posted by Jody Brown on October 30, 2001 at 4:41 AM

Yuan,

The important thing to remember here is that although a variable declared final cant be changed, the key here is that it cant be changed "once it has been initialised". Take the following example:-

public class MyClass {
    public final String myVariable;
    public String myMethod() {
        // here, myVariable can be initialised
        .
        .
        myVariable = "a value";
        // here, myVariable has been set and cannot be changed.
    }
}
