2．金额转换，阿拉伯数字的金额转换成中国传统的形式如：（￥1011）－>（一千零一拾一元整）输出。3、继承时候类的执行顺序问题,一般都是选择题,问你将会打印出什么?答:父类：packagetest;publicclassFatherClass{publicFatherClass(){System.out.println("FatherClassCreate");}}子类:packagetest;importtest.FatherClass;publicclassChildClassextendsFatherClass{publicChildClass(){System.out.println("ChildClassCreate");}publicstaticvoidmain(String[]args){FatherClassfc=newFatherClass();ChildClasscc=newChildClass();}}输出结果：C:>javatest.ChildClassFatherClassCreateFatherClassCreateChildClassCreate4、内部类的实现方式?答：示例代码如下：packagetest;publicclassOuterClass{privateclassInterClass{publicInterClass(){System.out.println("InterClassCreate");}}publicOuterClass(){InterClassic=newInterClass();System.out.println("OuterClassCreate");}publicstaticvoidmain(String[]args){OuterClassoc=newOuterClass();}}输出结果:C:>javatest/OuterClassInterClassCreateOuterClassCreate再一个例题：publicclassOuterClass{privatedoubled1=1.0;//insertcodehere}Youneedtoinsertaninnerclassdeclarationatline3.Whichtwoinnerclassdeclarationsarevalid?(Choosetwo.)A.classInnerOne{publicstaticdoublemethoda(){returnd1;}}B.publicclassInnerOne{staticdoublemethoda(){returnd1;}}C.privateclassInnerOne{doublemethoda(){returnd1;}}D.staticclassInnerOne{protecteddoublemethoda(){returnd1;}}E.abstractclassInnerOne{publicabstractdoublemethoda();}说明如下：一.静态内部类可以有静态成员，而非静态内部类则不能有静态成员。故A、B错二.静态内部类的非静态成员可以访问外部类的静态变量，而不可访问外部类的非静态变量；returnd1出错。故D错三.非静态内部类的非静态成员可以访问外部类的非静态变量。故C正确四.答案为C、E5、Java的通信编程，编程题(或问答)，用JAVASOCKET编程，读服务器几个字符，再写入本地显示？答:Server端程序:packagetest;importjava.net.*;importjava.io.*;publicclassServer{privateServerSocketss;privateSocketsocket;privateBufferedReaderin;privatePrintWriterout;publicServer(){try{ss=newServerSocket(10000);while(true){socket=ss.accept();StringRemoteIP=socket.getInetAddress().getHostAddress();StringRemotePort=":"+socket.getLocalPort();System.out.println("Aclientcomein!IP:"+RemoteIP+RemotePort);in=newBufferedReader(
