用java输出，从某年某月的某一天到另一个某年某月的某一天的，中间的所有日子，和判断是周几。

看代码吧

public class Test2 {

	/**
	 * 从year1年month2月到year2年到month2月的
	 * 
	 * @param args
	 */
	int days = 0;

	public static void main(String[] args) {
		int year1= 2013;
		int year2 = 2014;

		int month1 = 2;
		int month2 = 1;
		int day1 = 3;
		int day2 = 24;

		Test2 t = new Test2();
		t.printDay(year1, month1,day1, year2, month2,day2);

	}

	public void printDay(int year1, int month1,int day1, int year2, int month2,int day2) {
		int sum = 0;
