创建一个shell控制台(类似于windows中的cmd，unix中的bash等)在java中

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class ShellConsole {
    public static void main(String[] args) {
        try {
            ProcessBuilder processBuilder = new ProcessBuilder();
            processBuilder.command("cmd"); // Windows系统使用cmd命令
            // processBuilder.command("bash"); // Unix系统使用bash命令

            Process process = processBuilder.start();

            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }

            int exitCode = process.waitFor();
            System.out.println("Exit Code: " + exitCode);
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}
