For starters, you don't seem to understand the difference between a static and non-static method. Here is an example of how to call a method in a different class.
public class MainClass {
    public static void main(String[] args) {
        MainClass app = new MainClass();
        app.go();
    public void go() {
        System.out.println("start of go");
        another.method();
        System.out.println("end of go");
    private AnotherClass another = new AnotherClass();
public class AnotherClass {
    public void method() {
        System.out.println("method");
}
