use of "final" in variable declaration

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


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.
