Java 使用ProcessBuilder运行同一类的多个进程

我想要一个主类，用户在其中定义他们想要启动多少客户类流程。我该如何解决我的主要问题？下面是我用来运行Customer类一次的代码

try {       
        ProcessBuilder customer = new ProcessBuilder("java.exe","-cp","bin","lab_3.Customer");
        Process runCustomer = customer.start();

        runCustomer.waitFor();

    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

方法1，克隆 我不知道这是个多好的主意，但是，你可以尝试这样做：

ProcessBuilder customer = new ProcessBuilder("java.exe","-cp","bin","lab_3.Customer");
Process runCustomer = customer.clone().start();

.clone（）将复制它，然后从中启动进程。现在您可以执行以下操作：

ProcessBuilder customer = new ProcessBuilder("java.exe","-cp","bin","lab_3.Customer");
Process runCustomer1 = customer.clone().start();
Process runCustomer2 = customer.clone().start();
Process runCustomer3 = customer.clone().start();
Process runCustomer4 = customer.clone().start();

方法2，参数数组 您还可以将参数存储在一个数组中，每次您想要启动新的

进程

，您只需创建一个

ProcessBuilder

的新实例，如下所示：

String command = "java.exe";
String[] args = new String[]{ "-cp", "bin", "lab_3.Customer" };

for(int i = 0; i < numOfProcesses; i++) {
     new ProcessBuilder(command, args).start();
}

一个

for

循环应该可以做到这一点。

String command = "java.exe";
String[] args = new String[]{ "-cp", "bin", "lab_3.Customer" };
Process[] processes = new Process[numOfProcesses];

for(int i = 0; i < numOfProcesses; i++) {
     processes[i] = new ProcessBuilder(command, args).start();
}
