如何从方法中获取消息

public void processMessage(String message) {
    // 处理消息的逻辑
    System.out.println("收到消息：" + message);
}

String msg = "Hello, World!";
processMessage(msg);

def get_message():
    # 获取消息的逻辑
    return "Hello, World!"

msg = get_message()
print("收到消息：" + msg)

public class MessageProcessor {
    private string message;

    public void SetMessage(string msg) {
        message = msg;
    }

    public void ProcessMessage() {
        // 处理消息的逻辑
        Console.WriteLine("收到消息：" + message);
    }
}

MessageProcessor processor = new MessageProcessor();
processor.SetMessage("Hello, World!");
processor.ProcessMessage();
