FileSearch实现了操作系统文件夹中对文件名中含有指定字符串的查找，会在控制台输出所有符合条件的文件路径并且最终输出总数。
FileSearch2实现了操作系统文件夹中所有txt文件的查找，原理相同。FileOperation 接口是辅助接口，用于通用化文件迭代

账户类设定属性名称 密码 账户上的钱
主程序设定方法登陆 取款 查询 注销等
基本思路就是这样 具体写出来也不难 最好还是自己写吧

public class Account
{
privateString 账户ID;
private ...
private double 账户余额;

public void set账户余额(double num)
{
this.账户余额 = num;
}

public double get账户余额()
{
return 账户余额;
}

}

public class SyncDemo
{
private boolean 存钱(double num)
{
Account user1 = new Account();
try{
//锁数据
double 余额 = user1.get账户余额();
user1.set账户余额(余额 + num);
//解锁
return true;
}
catch(Exception e)
{
rollback;
return false;
}
}

private boolean 取钱(double num)
{

}

}

韦包硝酸： Name=Name.substring(0,1); Name=Name.substring(1); 你的Name变量值被冲掉,正确的是:String lastName=Name.substring(0,1); System.out.println(＂\n\n姓氏:＂+lastName); String firstName=Name.substring(1); System.out.println(＂名字:＂+firstName); 不过正如楼上说的,输入姓,名应该分开,并且中国和外国次序不一样.并且Java 里面变量首字母最好小写.

蓬安县19757185835： Java问题,急急急,求帮忙 - ？
韦包硝酸： 我是学c和c 的,不过我倒是能看懂你的这几句代码,你这里是用的递归算法吧,下面我们对你getvalue函数进行分析(一下简称get); 你给get的初值是6, 就运行getvalue(n-1) getvalue(n-2)= getvalue(6-1) getvalue(6-2)= getvalue(5) getvalue(4)...

蓬安县19757185835： 一个java程序问题,求答案?？
韦包硝酸： 简单的解决办法,点左边第一个X,选择第一项,目的:加上package 看看有没有用到File.count这个类,有的话去找找你复制的地方(这程序明显你复制的) 没有用到的话直接删掉着行
