按要求编写Java应用程序。
(1)创建一个叫做People的类:
属性:姓名、年龄、性别、身高
行为:说话、计算加法、改名
编写能为所有属性赋值的构造方法;
(2)创建主类:
创建一个对象:名叫“张三”,性别“男”,年龄18岁,身高1.80;让该对象调用成员方法:
说出“你好!”
计算23+45的值
将名字改为“李四”
public class shiyan10 {
public static void main(String[] arg){
People people=new People("张三",18,"男",1.80);
System.out.println("名字:"+people.name+"\t性别:"+people.sex+"\t年龄:"+people.age+"\t身高:"+people.height);
people.shuo("你好!");
people.suan(23,45);
people.gai("李四");
}
}
class People{
String name;
int age;
String sex;
double height;
People(String pname,int page,String psex,double pheight){
name=pname;
age=page;
sex=psex;
height=pheight;
}
String shuo(String hua){
System.out.println("说:"+hua);
return hua;
}
int suan(int a,int b){
System.out.println("计算结果:"+(a+b));
return a+b;
}
String gai(String ming){
System.out.println("改的名字:"+ming);
return ming;
}
}
