㈩ Java題
大致寫了一下，基本功能滿足，望採納
publicclassMingXing{
privateStringname;
privateStringsex;
privateintage;
privateStringdaiBiaoZuo;
publicMingXing(Stringname,Stringsex,intage,StringdaiBiaoZuo){
this.name=name;
this.sex=sex;
this.age=age;
this.daiBiaoZuo=daiBiaoZuo;
}
publicvoidshow(){
System.out.println("明星姓名："+name);
System.out.println("明星性別："+sex);
System.out.println("明星年齡："+age);
System.out.println("明星代表作："+daiBiaoZuo);
}
//set、get方法
publicvoidsetName(Stringname){
this.name=name;
}
publicStringgetName(){
returnname;
}
//TODO
}
