how to make a map of properties using formatted string "Property:Value"
问题
让我们假设我们创建了一个格式化的字符串，类似这样："Property:Value"。在Java中，如何将这个格式化的字符串放入一个HashMap<JoystickEnum, String>中，其中Property是一个enum，而值是一个string。目前我正在一个项目中工作，我们使用这种格式化的字符串接收输入。我的enum叫做JoystickEnum。这个类叫做Joystick，它扩展了Controller类。注意：由于我们将在多个控制器中实现这个抽象类，所以这个类有以下代码，
public String data;
public InputStream dataStream;
private byte[] readBuffer = new byte[400];
public enum InputMode {
POLL, EVENT
};
public InputMode mode = InputMode.EVENT;
public InputHandler(InputStream dataStream) {
this.dataStream = dataStream;
}
@Override
public abstract void serialEvent(SerialPortEvent arg0);
public void setDataMode(InputMode mode) {
this.mode = mode;
}
public abstract void poll();
public abstract Map getData();
@Override
public abstract void run();
InputMode枚举只包含POLL, EVENT。代码将放在扩展方法getData()中。

Lets say we created a string formatted like this "Property:Value". How do we put this formatted string into a map in Java like this HashMap<JoystickEnum,String> where Property is an enum and the value is a string. Currently I am working on a project where we recieve input using this formatted string. My enum is called JoystickEnum. The class is called Joystick and it extends the Controller class.NOTE: Since we will be using this abstract class that is going to be implemented in multiple controllers. This class has code,
public String data;
public InputStream dataStream;
private byte[] readBuffer = new byte[400];
public enum InputMode {
POLL,EVENT
};
public InputMode mode = InputMode.EVENT;
public InputHandler(InputStream dataStream) {
this.dataStream = dataStream;
}
@Override
public abstract void serialEvent(SerialPortEvent arg0);
public void setDataMode(InputMode mode) {
this.mode = mode;
}
public abstract void poll();
public abstract Map getData();
@Override
public abstract void run();
// TODO Auto-generated method stub
The InputMode enum just contains POLL,EVENT. Where the code will go is in the extended method getData()

如果data是格式为"Property:Value"的字符串，而map是类型为Map<JoystickEnum，String>的对象，则您可以按以下方式添加条目：
String[] dataArray = data.split(":");
map.put(JoystickEnum.valueOf(dataArray[0]), dataArray[1]);
假设Property与枚举值匹配，且Value不包含任何":"。
英文:
if data is a String of the format "Property:Value" and map an object of type Map<JoystickEnum, String> you can add an entry as follow
String[] dataArray = data.split(":");
map.put(JoystickEnum.valueOf(dataArray[0]), dataArray[1]);
assuming that Property match with an enum value and Value won't contain any ":"
