java调用windows命令并打印命令行输出

先来个主程序，这个程序用来读日志并且拷贝的，公司用的程序，不想改了，原封贴上:

package com.test;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;


public class TestF {
	public static void main(String[] args) {
		List list = readLog("d://Nopublic_log_2010-11-12_Y.txt");
		//checkFiles("f:\\user\\"+list.get(0).toString(),"J:\\178_f\\"+list.get(0).toString());
		for(int i =0;i<list.size();i++){
			System.out.println(list.get(i).toString());
			checkFiles("f:\\user\\"+list.get(i).toString(),"J:\\178_f\\"+list.get(i).toString());
		}
		System.out.println("over my test");
	}

	private static void checkFiles(String upload_Dir, String download_Dir) {
		try {
			File fold_download_Dir = new File(download_Dir);
			if(!fold_download_Dir.exists()){
				fold_download_Dir.mkdirs();
			}
			Runtime rt = Runtime.getRuntime();
			Process proc = rt.exec("xcopy /e "+upload_Dir+" "+download_Dir);
			StreamGobbler errorGobbler = new StreamGobbler(proc.getErrorStream(), "ERROR"); 
			StreamGobbler outputGobbler = new
			StreamGobbler(proc.getInputStream(), "OUTPUT");

			errorGobbler.start();
			outputGobbler.start();
			int exitVal = proc.waitFor();
			System.out.println("ExitValue: " + exitVal); 
			
		} catch (IOException e) {
			e.printStackTrace();
		} catch (InterruptedException e) {
			e.printStackTrace();
		}
	}


	private static List<String> readLog(String logpath) {
		InputStreamReader read = null;
		List<String> strs = new ArrayList<String>();
		File log = new File(logpath);
		try {
			read = new InputStreamReader(new FileInputStream(log));
			BufferedReader br = new BufferedReader(read);
			String data = null;
			while ((data = br.readLine()) != null) {
				strs.add(data.trim());
			}
		} catch (Exception e) {
			e.printStackTrace();
		} finally {
			return strs;
		}
	}
}

 接下来是StreamGobbler.java

package com.test;

import java.util.*;
import java.io.*;

public class StreamGobbler extends Thread {
	InputStream is;

	String type;

	public StreamGobbler(InputStream is, String type) {
		this.is = is;
		this.type = type;
	}

	public void run() {
		try {
			InputStreamReader isr = new InputStreamReader(is);
			BufferedReader br = new BufferedReader(isr);
			String line = null;
			while ((line = br.readLine()) != null)
				System.out.println(type + ">" + line);
		} catch (IOException ioe) {
			ioe.printStackTrace();
		}
	}
}
