怎么用java程序来执行jdb 命令呢

Answer 1

试试这个，在java.lang.Runtime中有很多方法可用的，你看看。
[code="java"]
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

public class TestRuntime
{
private static final String[] CMD_ITEMS = {"javac -g HelloWord.java", "jdb HelloWord", "stop at HelloWord:4", "run"};

public static void main(String[] args)
{
    Process process = null;
    try
    {
        for (String cmd : CMD_ITEMS)
        {
            System.out.println("命令 >>>>>> " + cmd);
            process = Runtime.getRuntime().exec(cmd);
            //执行命令      
            //取得命令结果的输出流      
            InputStream fis = process.getInputStream();
            //用一个读输出流类去读      
            InputStreamReader isr = new InputStreamReader(fis);
            //用缓冲器读行      
            BufferedReader br = new BufferedReader(isr);
            String line = null;
            //直到读完为止      
            while ((line = br.readLine()) != null)
            {
                System.out.println(line);
            }
        }

    }
    catch (IOException e)
    {
        System.out.println(e.getLocalizedMessage());
    }
}

}
