I have a problem with final

Hi friends,
I am new to this forum.
I am learning java now.
I have a problem in defining a constant using final .please help me.

Code:

---

class Testconst
{
public static void main(String args[])
{
static final double PI = 3.141592653589793;
System.out.println("pi="+pi);
//........
//.......
}
}

---

when i compiled this,i got an error like this
illegal start of expression
static final double PI = 3.141592653589793;

Is there any mistake in my code ?
please tell me.
Thank u very much.

Code:

C:\jexp>javac test.java
exptest.java:5: illegal start of expression
        static final double PI = 3.141592653589793;

Try either

Code:

---

public class Test {
    static final double PI = 3.141592653589793;

    public static void main(String[] args) {
        System.out.println("PI = " + PI);
    }
}

or

Code:

---

public class Test {
    public static void main(String[] args) {
        final double PI = 3.141592653589793;
        System.out.println("PI = " + PI);
    }
}
