Java终端进程切换

可以使用Java的ProcessBuilder类来启动多个命令行进程，并在它们之间进行切换。

示例代码：

public class ProcessSwitcher {

    public static void main(String[] args) throws IOException, InterruptedException {

        // 启动第一个进程并执行命令
        ProcessBuilder processBuilder1 = new ProcessBuilder("cmd.exe", "/c", "echo hello from process 1");
        Process process1 = processBuilder1.start();

        // 等待第一个进程执行结束
        process1.waitFor();

        // 启动第二个进程并执行命令
        ProcessBuilder processBuilder2 = new ProcessBuilder("cmd.exe", "/c", "echo hello from process 2");
        Process process2 = processBuilder2.start();

        // 等待第二个进程执行结束
        process2.waitFor();

        // 启动第三个进程并执行命令
        ProcessBuilder processBuilder3 = new ProcessBuilder("cmd.exe", "/c", "echo hello from process 3");
        Process process3 = processBuilder3.start();

        // 等待第三个进程执行结束
        process3.waitFor();

        // 切换到第一个进程并获取输出结果
        ProcessBuilder switchToProcess1Builder = new ProcessBuilder("cmd.exe", "/c", "tasklist /fi \"WINDOWTITLE eq hello from process 1\"");
        Process switchToProcess1Process = switchToProcess1Builder.start();
        BufferedReader switchToProcess1Reader = new BufferedReader(new InputStreamReader(switchToProcess1Process.getInputStream()));
        String switchToProcess1Output = switchToProcess1Reader.readLine();
        System.out.println(switchToProcess1Output);

        // 切换到第二个进程并获取输出结果
        ProcessBuilder switchToProcess2Builder = new ProcessBuilder("cmd.exe", "/c", "tasklist /fi \"WINDOWTITLE eq hello from process 2\"");
        Process switchToProcess2Process = switchToProcess2Builder.start();
        BufferedReader switchToProcess2Reader = new BufferedReader(new InputStreamReader(switchToProcess2Process.getInputStream()));
        String switchToProcess2Output = switchToProcess2Reader.readLine();
        System.out.println(switchToProcess2Output);

        // 切换到第三个进程并获取输出结果
        ProcessBuilder switchToProcess3Builder = new ProcessBuilder("cmd.exe", "/c", "tasklist /fi \"WINDOWTITLE eq hello from process 3\"");
        Process switchToProcess3Process = switchToProcess3Builder.start();
        BufferedReader switchToProcess3Reader = new BufferedReader(new InputStreamReader(switchToProcess3Process.getInputStream()));
        String switchToProcess3Output = switch
