java 如何用线程，实现将1-100000.txt的内容读出来，再写到a.txt文件里

Answer 1

在一个线程循环查看文件，把文件写入a.txt就OK了啊
如果用线程不就乱拉

Answer 2

你看看这样可不?

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;

public class Test {

public static void main(String[] args) {
new ResultThread(new File("D:\\test")).start();
}
}

class ResultThread extends Thread {

File root = null;
File result = null;

public ResultThread(File root) {
this.root = root;
result = root.getParentFile();
}

public void run() {
FileInputStream fin = null;
FileOutputStream fout = null;
try {
result = new File(result, "a.txt");
fout = new FileOutputStream(result);
int len = 0;
byte[] buff = new byte[4096];

for (int i = 1; i <= 10000; i++) {
try {
fin = new FileInputStream(new File(root, i + ".txt"));
while ((len = fin.read(buff)) != -1) {
fout.write(buff, 0, len);
}
} catch (Exception e) {

}
fin.close();
sleep(100);
}

} catch (Exception e) {

} finally {
try {
fout.close();
fin.close();
} catch (Exception e) {

}
}

}
}

什么意思，把100000个txt文件的内容读出来，按顺序写到a.txt里面？
这跟线程有什么关系
