JAVA如何调用exe或者批处理文件

/**

 import java.lang.Runtime;
 import java.lang.Process;
 import java.io.InputStreamReader;
 import java.lang.Exception;
 import java.io.*;
public class JavaExec {
     /**

	public static void main(String[] args) {
		// TODO Auto-generated method stub
           
		JavaExec javaExec = new  JavaExec();
		javaExec.testProcess();
	}
	
	public void testProcess()  
    {  
        try  
        {  
		
        String home="c:/process";  
        String command = "bfimport.bat -U yq -P qq -x bfimport_71.xml  -p";  
		String[] cmd = new String[] { "cmd.exe", " ", "bfimport.bat" };   
        File dir = new File(home);  
        //Process process = Runtime.getRuntime().exec(command,null, dir);  
		Process process = Runtime.getRuntime().exec(command);  
        
        /*TestInputStream errorStream = new TestInputStream(process
		    .getErrorStream());
	    errorStream.start();*/
	    InputStream  inputStream = process.getInputStream();
		BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));   
		
		String line = null;  
        while ((line = reader.readLine()) != null) {  
                    System.out.println(line);  
        } 
		 //int exitValue = process.waitFor();  
         //System.out.println("Return Value:" + exitValue);  
         process.getOutputStream().close(); 
        }  
        catch(IOException e)  
        {  
            System.out.println("IOException ");

修改其中的command就可以了

上面的例子确实可以获得一些输出，但是有很多情况也无法获取，再参考很多实例之后，下面的例子最强大，几乎可以捕获所有类型的命令行输出。
