Java调用CMD命令的方法与使用技巧

import java.io.*;
public class CmdExecutionExample {
    public static void main(String[] args) {
        try {
            // 调用CMD命令
            String command = "ipconfig";
            Process process = Runtime.getRuntime().exec(command);
            // 获取命令输出结果
            InputStream inputStream = process.getInputStream();
            BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, "GBK")); // 设置编码为GBK
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }
            // 等待命令执行完成
            process.waitFor();
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}
