java表格代码怎么写

java表格就是java swing。

//创建表头

String[] columnNames = { "First Name", "Last Name", "Sport",

"# of Years", "Vegetarian" };

//创建显示数据

Object[][] data = {

{ "Kathy", "Smith", "Snowboarding", new Integer(5),

new Boolean(false) },

{ "John", "Doe", "Rowing", new Integer(3), new Boolean(true) },

{ "Sue", "Black", "Knitting", new Integer(2),

new Boolean(false) },

{ "Jane", "White", "Speed reading", new Integer(20),

new Boolean(true) },

{ "Joe", "Brown", "Pool", new Integer(10), new Boolean(false) } };

/*

* JTable还提供了一个重载的构造方法,传入两个Vector

* JTable(Vector rowData, Vector columnNames)

*

*/

final JTable table = new JTable(data, columnNames);

table.setBackground(Color.YELLOW);

要求编写一个java程序,输入学生信息,并能保存与显示学生信息。

import java.util.ArrayList;

import java.util.Scanner;import com.sun.org.apache.xpath.internal.Arg;

public class Student {

//两个私有属性

private int no ;

private String name ;

//默认构造函数

public Student(){}

//带参构造函数

public Student(int no,String name){

this.no=no;

this.name=name;

}

//添加学生信息

public void addStudentInfo(ArrayList list){

String flag1="yes";

do{

Student student=new Student();

Scanner in =new Scanner(System.in);

System.out.println("请输入学生学号:");

student.setNo(in.nextInt());

System.out.println("请输入学生姓名:");

student.setName(in.next());

list.add(student);

System.out.println("是否继续添加学生信息(yes/no)?");

flag1=in.next();

} while(flag1.equals("yes"));

}

//读取学生信息

public void showStudentInfo(ArrayListStudent list){

System.out.println(" 学生no: "+" 学生name: ");

for(Student student:list){

System.out.println(" "+student.getNo()+" "+student.getName());

}

}

public int getNo() {

return no;

}

public void setNo(int no) {

this.no = no;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public static void main(String arg[]) {

ArrayListStudent studentList= new ArrayListStudent();

Student student= new Student();

Scanner inn= new Scanner(System.in);

while(true){

System.out.println("----------------- 欢迎使用学生管理系统------------------");

System.out.println("1.输入学生信息");

System.out.println("2.显示学生信息");

System.out.println("0.退出系统");

System.out.println("请选择....");

int nn= inn.nextInt();

switch (nn) {

case 1:

student.addStudentInfo(studentList);

break;

case 2:

System.out.println("学生信息如下:");

student.showStudentInfo(studentList);

break;

case 0:

System.exit(0);

System.out.println("系统退出!");

break;

default:

break;

}

}

} }

int i=0;

while(rs.next()){

content[i]=rs.getString(1);//content是你声明号的数组

用Java怎样实现课表代码?有周次

课表数据时存储于数据库中的吗?

/**

* 获取一周的时间集合(从周一到周日)

* @param weekNum ;-1:上周;0:本周;1:下周

*/

public static ListDate getWeekDates(int weekNum){

ListDate list = new ArrayListDate();

Calendar cal = Calendar.getInstance();

// 获取指定下几个星期

cal.add(Calendar.DAY_OF_WEEK, weekNum * 7);

cal.setFirstDayOfWeek(Calendar.MONDAY);

cal.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY);

list.add(cal.getTime());

for(int i = 0;i 6;i++){

cal.add(Calendar.DAY_OF_WEEK, 1);

list.add(cal.getTime());

}

return list;

}

这个是获取这一周时间的代码 ,之后用下面的代码获取周一到周日的日期

ListDate ds = DateUtil.getNowWeekDates(weekNum);

ds.get(0)//周一

ds.get(6)//周日

用这两个时间到数据库中进行范围查询,之后的你应该明白了吧
