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();
}
}
}
}
}
