Why Won't This Simple Program Run?

[Gary Farms]

I have 2 files. I call the method MyFunc in MyClass.java from main in MyTest.java. That's all I'm trying to do. I put them both in the same package, and it still won't run. I now get a run-time error saying "NoSuchMethod" when I run MyTest. Why??
Also, is there no way to call a method (via the import statement) without extending it's class, and putting both the caller class and the callee class in the same package?
Anyway, here's my 2 files:
Here's Mytest.java:
package com.util;
public class MyTest extends MyClass
{
public void main (String[] args)
{
MyTest obj = new MyTest();
obj.MyFunc();
}
}
And here's my MyClass.java file:
package com.util;
public class MyClass
{
public void MyFunc()
{
Suystem.out.println("Printed from MyFunc");
}
}

In MyTest.java, signature of the main() method should be:
public static void main(...

The only way to make MyClass.MyFunc() visible from a different package would be to either make it public or make it protected call it from a class that extends MyClass. The import statement will not help you do this in any way--that is not its purpose.
the following should work:

/* MyClass.java */
package com.util;
public class MyClass {
    /* package access */
    void myFunc() {
        System.out.println("in MyClass.myFunc()");
    }
}

/* MyTest.java */
package com.util;
public class MyTest {
    public static void main(String[] args) {
        MyClass obj = new MyClass();
        obj.myFunc();
    }
}

Compile with the following commands:
javac -d c:\java\com\util MyClass.java
javac -d c:\java\com\util MyTest.java
Run with:
java com.util.MyTest

Gary, the following also works:

// File com/util/MyClass.java
package com.util;
public class MyClass
{
    public void MyFunc()
    {
        System.out.println("Printed from MyFunc");
    }
} 
// File MyTest.java
import com.util.MyClass;
public class MyTest
{
    public static void main (String[] args)
    {
        MyClass obj = new MyClass();
        obj.MyFunc();
    }
}

From the command line:

Sorry, Roy. Doesn't seem like I did much better than you did.

Sorry, bartender; I can't seem to format my previous message in a graceful way. Any hints?

It would be better if you continue the same thread, Gary, rather than starting several. This way several people don't give the same answer in various places. I'm closing this one.
