请教一个Java问题

Question

设计一个标题为“随机点名器’的窗体，添加一个“点名”按钮、“点名结果”标签和文本区组件,单击“点名”按钮后随机选择姓名数组中的名字，并将点到的姓名追加在文本区中。此窗体带关闭功能。 随机点名出来了，窗口不会弄。 package test01; import java.util.Random; import java.util.Scanner; public class CallName { public static void addStudentName (String[] students) { Scanner sc = new Scanner ( System.in) ; for (int i = 0; i < students.length; i++) { System.out.println ("存储第"+ (i+1) +"个姓名: "); students[i] = sc.next (); } } public static void printstudentName (String[] students){ for (int i = 0; i < students. length; i++) { String name = students[i]; System.out.println ("第"+ (i+1) +"个学生姓名:”+ name"); } } public static String randomStudentName (String[] students) { int index = new Random (). nextInt (students. length) ; String name = students [index]; return name; } /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub System. out.println(" 随机点名器 ") ; String[] students = new String[3]; addStudentName (students) ; printStudentName (students) ; String randomName = randomStudentName(students) ; System.out.println("被点到名的同学是:"+ randomName) ; } }

用Swing写界面就可以了，学生资料是写死的，还是要录入呢？
