如何用Java实现Ping
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怎样实现ping的功能...
可以用InetAddress的isReachable方法：
import java.net.InetAddress;
public class MainTest {
public static void main(String[] args) {
try {
int timeOut = 3000;
byte[] ip = new byte[] { (byte) 192, (byte) 168, (byte) 100, (byte) 151 };
int retry = 4;
InetAddress address = InetAddress.getByAddress(ip);
for (int i = 0; i retry; i++) {
if (address.isReachable(timeOut)) {
System.out.println(i + " OK");
} else {
System.out.println(i + " LOSS");
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
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);
}
}
