How can I determine the logic used for naming the synthetic attribute created inside enums to store the values of it in Java? I've been trying to find either documentation without luck, I also looked at the source to see if I was able to get some more insight on my own. So far the...

Introduction to Using Interfaces in Java Enums In Java, enums are a special kind of class that can contain constants and methods. They provide a way to define a set of named values, often representing a fixed number of options or choices. One powerful feature of Java enums is their abili...
Enums are often used inswitchstatements to check for corresponding values: Example enumLevel{LOW,MEDIUM,HIGH}publicclassMain{publicstaticvoidmain(String[]args){LevelmyVar=Level.MEDIUM;switch(myVar){caseLOW:System.out.println("Low level");break;caseMEDIUM:System.out.println("Medium level");break;...
VALUES ( #{item.status} ) </insert> <select id="getOrderById" resultType="com.yulaiz.model.order.entity.OrderInfo"> SELECT id, status FROM order_test WHERE id = #{id} </select> 1.4 代码效果 我们最后拿到的就是0,1,2,3,4这样的数值来表示订单状态了,当然现在的例子实在简单,实际项目中,...

javaenums 4 我必须使用 switch 语句来获取枚举值。这是枚举: public enum Compass { NORTH, SOUTH, EAST, WEST; } 我在枚举外的另一个类中执行了以下操作: Compass.values()[0].name() 但是这本书说实现的方法是: Compass[] comp = { Compass.NORTH, Compass. SOUTH, Compass.EAST, Compass.WES...
For example, if we have an enum OrderStatus with values PENDING, IN_PROGRESS, COMPLETED, and CANCELED, the default behavior would store them as integers 0, 1, 2 and 3, respectively. The resulting database table would have a status column of type smallint, with values 0 to 3: creat...
You can add fields to a Java enum. Thus, each constant enum value gets these fields. The field values must be supplied to the constructor of the enum when defining the constants. Here is an example: public enum Level { HIGH (3), //calls constructor with value 3 ...
