java线程创建怎么调试

public class MyThread extends Thread {
    @Override
    public void run() {
        System.out.println("Thread created: " + this);
        // Your code here
    }
}

import com.sun.jdi.*;
import com.sun.jdi.connect.*;

public class JdiThreadExample {
    public static void main(String[] args) {
        // Create a connection to the target Java application
        VirtualMachineManager vmm = Bootstrap.virtualMachineManager();
        AttachingConnector connector = vmm.attachingConnectors().get(0);
        Map<String, Connector.Argument> arguments = connector.defaultArguments();
        arguments.get("port").setValue("8000");

        try {
            // Attach to the target process
            VirtualMachine vm = connector.attach(arguments);

            // Create a new thread in the target process
            ThreadReference thread = vm.allThreads().get(0);
            thread.create();

            // Detach from the target process
            vm.dispose();
        } catch (IOException | IllegalConnectorArgumentsException e) {
            e.printStackTrace();
        }
    }
}
