我可以在cmd中从JAR执行多个程序吗？

@echo off
java -jar program1.jar
java -jar program2.jar
java -jar program3.jar

@echo off
start java -jar program1.jar
start java -jar program2.jar
start java -jar program3.jar

@echo off
if %condition%==true (
    java -jar program1.jar
) else (
    java -jar program2.jar
)

public class MainProgram {
    public static void main(String[] args) {
        try {
            ProcessBuilder pb1 = new ProcessBuilder("java", "-jar", "program1.jar");
            ProcessBuilder pb2 = new ProcessBuilder("java", "-jar", "program2.jar");
            ProcessBuilder pb3 = new ProcessBuilder("java", "-jar", "program3.jar");

            Process process1 = pb1.start();
            Process process2 = pb2.start();
            Process process3 = pb3.start();

            // 等待所有进程完成
            int exitCode1 = process1.waitFor();
            int exitCode2 = process2.waitFor();
            int exitCode3 = process3.waitFor();

            System.out.println("Program 1 exited with code " + exitCode1);
            System.out.println("Program 2 exited with code " + exitCode2);
            System.out.println("Program 3 exited with code " + exitCode3);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
