前些天机房中了病毒，jcreator坏了，editplus也用不起来那时只好用批处理给学生上课，想自己写个简单点的编译方式终于知道如何捕获输出了，学期也结束了：

import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;

/*** Created on 2004-5-23* @author yuchifang* 测试如何执行本地程序并捕获out和err输出*/public class TestInOutErr{ public static void main(String[] args) throws IOException { Process p = Runtime.getRuntime().exec("java test"); BufferedReader in = new BufferedReader( new InputStreamReader(p.getInputStream())); String currentLine = null; while ((currentLine = in.readLine()) != null) System.out.println(currentLine); BufferedReader err = new BufferedReader( new InputStreamReader(p.getErrorStream())); while ((currentLine = err.readLine()) != null) System.out.println(currentLine); }}
