java能调用linux的ping方法吗

Answer 1

能啊
使用Runtime.getRuntime().exec(cmd)就行
给你个简单的例子：
public class ExecExample {

public static String exec(String cmd) {
Process p;
try {
p = Runtime.getRuntime().exec(cmd);
} catch (IOException e) {
return null;
}
Reader reader = new InputStreamReader(p.getInputStream());
StringBuilder sb = new StringBuilder();
char[] buffer = new char[512];
while (true) {
int read;
try {
read = reader.read(buffer);
} catch (IOException e) {
break;
}
if (read < 0) {
break;
}
sb.append(buffer, 0, read);
}
try {
reader.close();
} catch (IOException e) {
}
return sb.toString();
}

public static void main(String[] args) throws IOException {
System.out.println(exec("ping -c 4 www.baidu.com"));
}

}
