在java中如何调用批处理程序

Question

如何在程序中通过java代码调用机器上C:\temp\test.bat？？

Answer 1

import java.io.*;
public class Run{
    public static void main(String rags[])throws Exception{
     Process p=Runtime.getRuntime().exec("C:\\temp\\test.bat");
 InputStream in=p.getInputStream();
 int ch=-1;
     while((ch=in.read())!=-1);
}
}

Answer 2

Process pro = Runtime.getRuntime().exec("C:\\test.bat");//这里调用批处理
InputStreamReader isrErr = new InputStreamReader(pro.getErrorStream());//这里得到错误输出流
BufferedReader brErr = new BufferedReader(isrErr);

Answer 3

//一个批处理和和得到批处理的输出流和错误流的例子
public class JavaCammandTest {

public static void main(String [] args){
T.test();
}

public static void test() throws IOException{
FileWriter fwErr = new FileWriter(new File("C:\\err.txt"));
BufferedWriter bwErr = new BufferedWriter(fwErr);
FileWriter fwOut = new FileWriter(new File("C:\\Out.txt"));
BufferedWriter bwOut = new BufferedWriter(fwOut);

Process pro = Runtime.getRuntime().exec("C:\\test.bat");
InputStreamReader isrErr = new InputStreamReader(pro.getErrorStream());
BufferedReader brErr = new BufferedReader(isrErr);

String s;
while((s = brErr.readLine()) != null){
bwErr.write(s);
bwErr.newLine();
}
brErr.close();
bwErr.close();

InputStreamReader isrIn = new InputStreamReader(pro.getInputStream());
BufferedReader brIn = new BufferedReader(isrIn);

while((s = brIn.readLine()) != null){
bwOut.write(s);
bwOut.newLine();
}
brIn.close();
bwOut.close();

pro.destroy(); }
}
