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;

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);
}
}
