您可以使用
Process对象执行命令，也可以使用读取该对象的输出
BufferedReader，这是一个快速的示例，可以帮助您：
import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;public class Main { public static void main(String args[]) { try { Process proc = Runtime.getRuntime().exec("cmd set PATH=%PATH%;C:\Something\bin"); proc.waitFor(); BufferedReader reader = new BufferedReader(new InputStreamReader(proc.getInputStream())); String line = reader.readLine(); while (line != null) { //Handle what you want it to do here line = reader.readLine(); } } catch (IOException e1) { //Handle your exception here } catch(InterruptedException e2) { //Handle your exception here } System.out.println("Path has been changed"); }}
