Java中如何对枚举值进行比较呢?

实现思路:
    java中比较枚举值
	只需使用“==运算符”即可对其进行比较

//枚举定义
Language.java

package com.java265.java
 
public enum Language {
    JAVA,
    PYTHON,
    NODE,
    NET,
    RUBY
}

枚举比较方法一:if 语句判断

package com.java265.java
 
public class Test {
 
    public static void main(String[] args) {
 
		// Covert string to enum
        //Language enumObj = Language.valueOf("java".toUpperCase());
 
        Language enumObj = Language.JAVA;
		
        if (enumObj == Language.JAVA) {
            System.out.println("Welcome Java");
        } else if (enumObj == Language.NET) {
            System.out.println("Welcome .Net");
        } else if (enumObj == Language.NODE) {
            System.out.println("Welcome Node JS");
        } else if (enumObj == Language.PYTHON) {
            System.out.println("Welcome Python");
        } else if (enumObj == Language.RUBY) {
            System.out.println("Welcome Ruby");
        } else {
            System.out.println("Hello World");
        }
 
    }
 
}

枚举比较方法二:switch语句比较

package com.java265.java
public class Test2 {
    public static void main(String[] args) {
        Language enumObj = Language.PYTHON;
 
        switch (enumObj) {
            case JAVA:
                System.out.println("Welcome Java");
                break;
            case NET:
                System.out.println("Welcome .Net");
                break;
            case NODE:
                System.out.println("Welcome Node JS");
                break;
            case PYTHON:
                System.out.println("Welcome Python");
                break;
            case RUBY:
                System.out.println("Welcome Ruby");
                break;
            default:
                System.out.println("Hello World");
                break;
        }
    }
}
