Final variables

[Bharadwaj Adepu]

public class Test {
public final String name;
public Test(String name){
this.name=name;
}
static public void main(String a[]) {
System.out.print(new Test("FINAL VARIABLE").name);
}
}

In the above code the constructor is setting a value to the final variable name.
How is that possible? This runs fine and prints FINAL VARIABLE!
Please explain.

[Campbell Ritchie]

A final field or variable can be set up once and once only. That can be done at declaration, in an initialiser (fields only) or in the constructor (again fields only).
