How to call a method in one class to another class

[sicarie]

lol. Java.sun.com is your friend! Math is "public final class". (which is cool because I never knew they existed.)

Math Class

Yeah, ever tried to create a class that you cannot copy/inherit? public final classes are fun, but most people also forget to overload the copy constructor...

There we go:

By default many of the Math methods simply call the equivalent method in StrictMath for their implementation

Instead of complicating matters even further: it was a compilation problem: the
compiler couldn't find class 'first' (bad name by the way for a class).

I already answered the OP in reply #10. It's another classpath issue again.

kind regards,

/* first.java */
package test;
public class first
{
 public static void display()
{
 System.out.println(" welcome to java");
}
}

/*second.java */
package test;
public class second
{
 void check()
   {
    first.display();
  }
}

I have stored above code in test folder. first.java is compiled successfully. When I am compiling second.java , I got the following error message
"cannot resolve the symbol variable first".

How to correct this error?

Hi
you are trying to access the method without creating the object of the class.
create the object of class first and then access the method associated with it.

No that is not needed; read the thread and you'll notice that it's (just) a classpath
issue.
