How do I create a library of common methods without instantiating a
class which gives me access to the method? I know how to create a
library that has a class and the method. I can then:

CommonCode cc = new CommonCode();
String result = cc.myMethod();

This works fine but what I want to do is have the library contains
methods so I don't have to instantiate the class: I want to just do:

String result = myMethod();

Again, I know I can place it in my project but I want the library
available for many projects.

static

class myUtils {
    public static String myMethod() {
        return "hello world!";
    }
}

System.out.println(myUtils.myMethod());

Class names should start with an upper-case letter.

OP: The 'System.out' call that Knute showed will itself be invoked from some
other method, not standalone. He's just illustrating that 'static' methods
will do what you asked.

You should read the Java tutorials. Then read more advanced stuff. These
questions are answered in the tutorials, though.
