a static method can only access static members... or constructors. Once you construct the object, you can call it's non-static methods. a common idiom you'll see is

public class SomeClass {
public static void main(String args[]) {
SomeClass myInstance = new SomeClass();
myInstanct.callAMethod();
}
public void callAMethod(){
//do something
}

}


There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors
