附录：主要源程序
(1) Disk.java

求一个java程序代码
package Test1;
import java.time.LocalDateTime;
import java.time.Month;
import java.util.IntSummaryStatistics;
import java.util.Scanner;
import java.util.Vector;
public class D {
static String s1 = "";
public static void main(String[] args) {
int day = LocalDateTime.now().getDayOfMonth();
Month month = LocalDateTime.now().getMonth();
int i = 1, i1 = 0;
VectorInteger vector=new Vector();
Scanner scanner = new Scanner(System.in);
while (i day + 1) {
System.out.println("请输入" + month + "月" + i + "日走的步数");
try {
i1 = scanner.nextInt();
} catch (Exception e) {
// TODO: handle exception
System.out.println("输入错误,请重新输入");
continue;
}
vector.add(i1);
i++;
}
scanner.close();
IntSummaryStatistics intSummaryStatistics=vector.stream().mapToInt(x-x).summaryStatistics();
int i2=intSummaryStatistics.getMax();
int i3=vector.indexOf(i2);
System.out.println(month+"月走的步数最多的日期为: "+(i3+1)+"号");
System.out.println("最多的步数为: "+i2);
}
}
java 马走日 两点最小步数 用队列
以下是两个线程：
import java.util.*;
public class Thread_List_Operation {
//假设有这么一个队列
static List list = new LinkedList();
public static void main(String[] args) {
Thread t;
t = new Thread(new T1());
t.start();
t = new Thread(new T2());
t.start();
}
}
//线程T1,用来给list添加新元素
class T1 implements Runnable{
void getElemt(Object o){
Thread_List_Operation.list.add(o);
System.out.println(Thread.currentThread().getName() + "为队列添加了一个元素");
}
@Override
public void run() {
for (int i = 0; i 10; i++) {
getElemt(new Integer(1));
}
}
}
//线程T2,用来给list添加新元素
class T2 implements Runnable{
void getElemt(Object o){
Thread_List_Operation.list.add(o);
System.out.println(Thread.currentThread().getName() + "为队列添加了一个元素");
}
@Override
public void run() {
for (int i = 0; i 10; i++) {
getElemt(new Integer(1));
}
}
}
//结果（乱序）

各位大侠，请帮忙用Java，在学生管理系统中添加上传照片功能，或者在象棋游戏中添加计时和计算步数功能，
这张照片是合成图片，里面的照片用最普通的卡片机就能拍出来，不需要特殊技术或镜头。
你觉得漂亮大概是因为他对图片进行后期编辑的结果。色彩的搭配，图片的裁切组合，形成一定的形式感，给你了不同于最平常的那种照片的视觉体验。
当你的眼界更加开阔就可以看出照片还可以拍的更好，后期处理也可以做的更好。
统计鼠标点击步数用java实现
问题看不懂,如果是 web项目的话 可以把点击次数存数据库里面,每点一下读取后,再存库;
如果是用java类来实现控制台输出之类的;那么需要把点击次数存到一个txt文件里面,
用字符流读入,和写出
