Can someone explain these statements abt Java?

Question

Can someone explain these statements abt Java:
+"The lesson for language designers is that *invocations of class and instance method* should look different from each other.+
+One way to future this goal is to *disallow the use of expressions as qualifiers* for static methods.+
+A second way to distinguish static and instance method invocations is to *use different operators*, as C++ does.+
+A third alternative is to finesse the issue by *dispensing with the concept of static methods altogether*, as Smalltalk does."+
esp those parts in bold, preferable with examples in explanationThanks!

static versus non-static methods.
public class Foo
    public static void aClassMethod() { System.out.println("I'm a class method for " + Foo.class.getName());
    public void anInstanceMethod() { { System.out.println("I'm an instance method for " + Foo.class.getName());
    public static void main(String [] args)
        Foo.aClassMethod();
        Foo f = new Foo();
        f.anInstanceMethod();
