java开发_快速搜索本地文件_小应用程序

先来看看效果：

这是一个Application运行效果

然后我突发奇想，我之前做过一个Application叫做：java开发_java小程序_邮死你(yousini)_源码下载

为什么不去修改它的源代码，把这个功能实现在一个桌面应用程序中去呢？

就这样有一个java小程序就这样诞生啦....

上面的Application代码：

    // 主方法

            new Thread(td).start();

    }

    // 重写run方法

    }

                }
                count++;
            }
        }
        return count;
    }

    public String getPostfix(String inputFilePath) {
        return inputFilePath.substring(inputFilePath.lastIndexOf(".") + 1);
    }

}
