如何用java执行命令行

Java运行命令行并获取返回值，下面以简单的Java执行ping命令（ping 127.0.0.1 -t

）为例，代码如下：

Process p = Runtime.getRuntime().exec("ping 127.0.0.1 -t");

Process p = Runtime.getRuntime().exec("javac");

InputStream is = p.getInputStream();

BufferedReader reader = new BufferedReader(new InputStreamReader(is));

String line;

while((line = reader.readLine())!= null){

System.out.println(line);

}

p.waitFor();

is.close();

reader.close();

p.destroy();

}

Java代码调用cmd中的ping命令.如何获得ping返回的信息?

public static void main(String[] args) throws IOException, InterruptedException {

// 执行ping命令

String cmdPing = "ping 127.0.0.1";

Runtime run = Runtime.getRuntime();

Process process = run.exec(cmdPing);

process.waitFor();

BufferedReader br = new BufferedReader(new     InputStreamReader(process.getInputStream(), Charset.forName("GBK")));

String line = null;

while ((line = br.readLine()) != null) {

System.out.println(line);

}

}

用java怎么实现调用cmd，并执行ping命令，求完整的语句

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStream;

import java.io.InputStreamReader;

public class Test {

public static void main(String[] args) {

Runtime rt = Runtime.getRuntime();

try {

Process p = rt.exec("cmd /c ping -t");

InputStream is = p.getInputStream();

BufferedReader br = new BufferedReader(new InputStreamReader(is));

String temp = null;

while((temp =br.readLine()) != null){

System.out.println(temp);

}

} catch (IOException e) {

e.printStackTrace();

}

}

}

如何java编程实现PING命令

你应该看看api process 返回的是流,按照输出流的方法操作即可.公司上不去外网,有代理才行,所以没有ping 百度,ping的本机.

import java.io.BufferedReader;

import java.io.InputStreamReader;

public class CallCmd {

public static void main(String[] args) {

BufferedReader br = null;

try {

Process p = Runtime.getRuntime().exec("ping 127.0.0.1");

br = new BufferedReader(new InputStreamReader(p.getInputStream()));

String line = null;

StringBuilder sb=new StringBuilder();

while ((line = br.readLine()) != null) {

sb.append(line+"\n");

}

System.out.println(sb.toString());

} catch (Exception e) {

e.printStackTrace();

} finally {

if (br != null) {

try {

br.close();

} catch (Exception e) {

e.printStackTrace();

}

}

}

}

}

java exce ping命令

String line = null;

while((line = br.readLine()) != null){

System.out.println(line);

}
