"cannot resolve symbol" help..

Question

Here is a very short and simpel program that won't compile after I reinstalled java on my computer.
import java.lang.Math.*;
import java.awt.*;
public class PiTest extends Frame {
     public static void main(String[] p){
     System.out.println("testing MATHs");
     System.out.println(""+sin(10));
I get the following error:
PiTest.java:8: cannot resolve symbol
symbol : method sin (int)
location: class PiTest
System.out.println(""+sin(10));
^
[total 1553ms]
1 error
Why doesn't the compiler recognise the sine function? I have set my classpath to c:\j2sdk1.4.1_01\lib.
I don't know what I'm doing wrong...

Answer 1

Replace sin(10) with Math.sin(10), it should work.
import java.lang.Math.*;
import java.awt.*;
public class PiTest extends Frame {
public static void main(String[] p){
System.out.println("testing MATHs");
//System.out.println(""+sin(10));
System.out.println(""+Math.sin(10));
