用Java调用Linux终端:如何刷新输出？

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

public class JavaLinuxTerminal {
    public static void main(String[] args) {
        try {
            // 运行Linux命令
            Process process = Runtime.getRuntime().exec("your-command-here");

            // 读取命令的输出
            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }

            // 等待命令执行完成
            process.waitFor();

            // 关闭输入流
            reader.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

import java.io.PrintStream;

public class JavaLinuxTerminal {
    public static void main(String[] args) {
        try {
            // 创建一个新的进程
            ProcessBuilder processBuilder = new ProcessBuilder("your-command-here");

            // 重定向输出到PrintStream对象
            Process process = processBuilder.start();
            PrintStream printStream = new PrintStream(process.getOutputStream());

            // 刷新输出
            printStream.println();

            // 关闭输出流
            printStream.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
