4、定義兩個類,描述如下: [必做題]
4.1定義一個人類Person:
4.1.1定義一個方法sayHello(),可以向對方發出問候語“hello,my name is XXX”
4.1.2有三個屬性:名字、身高、體重
4.2定義一個PersonCreate類:
4.2.1建立兩個對象,分别是zhangsan,33歲,1.73;lishi,44,1.74
4.2.2分别調用對象的sayHello()方法。
public class People {
String name;
int age;
double height;
void sayHello(){
System.out.println("hello,my name is "+this.name+"\n身高是:"+this.height+"\n年齡是:"+this.age);
}
void add(String name,int age,double height) {
this.name =name;
this.age = age;
this.height = height;
}
}
public class People1 {
public static void main(String[] args) {
People p1 = new People();
p1.add("張三",33,1.73);
p1.sayHello();
People p2 = new People();
p2.add("李四",44,1.74);
p2.sayHello();
}
}
