/**
* 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

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);
