JAVA 工作指南 可以说是程序员必备的东西哦

import java.util.*;

public class Class1 {
    protected InnerClass1 ic;

    public Class1() {
        ic = new InnerClass1();
    }

    public void displayStrings() {
        System.out.format("%s.%n", ic.getString());
        System.out.format("%s.%n", ic.getAnotherString());
    }

    static public void main(String[] args) {
        Class1 c1 = new Class1();
        c1.displayStrings();
    }

    protected class InnerClass1 {
        public String getString() {
            return "InnerClass1: getString invoked";
        }

        public String getAnotherString() {
            return "InnerClass1: getAnotherString invoked";
        }
    }
}
