編寫Java應用程序。首先,定義描述學生的類——Student,包括學號(int)、姓名(String)、年齡(int)等屬性;二個方法:Student(int stuNo,String name,int age)
用於對對象的初始化,outPut()用於輸出學生信息。其次,再定義一個主類—TestClass,在主類的main方法中創建多個Student類的對象,使用這些對象來測試Student類的功能。
1 //創建類
2 int stuNo;
3 String stuName;
4 int stuAge;
5 //構造方法
6 student(int stuNo,String name,int age)
7 {
8 this.stuNo=stuNo;
9 stuName=name;
10 stuAge=age;
11 }
12 void outPut()
13 {
14 System.out.println(stuName+"\t"+stuNo+"\t"+stuAge);
15 }
16
17 public static void main(String[] args) {
18 student xs1=new student(10001,"張三",25);
19 student xs2=new student(10002,"李四",27);
20 student xs3=new student(10003,"王五",22);
21 student xs4=new student(10004,"馬六",19);
22 student xs5=new student(10005,"馮七",22);
23 student xs6=new student(10006,"秦八",26);
24
25 System.out.println("姓名:\t學號:\t年齡:");
26 xs1.outPut();
27 xs2.outPut();
28 xs3.outPut();
29 xs4.outPut();
30 xs5.outPut();
31 xs6.outPut();
32 }
運行結果:
