获取枚举名称示例

以下示例演示了枚举的 name() 方法的用法。

package com.tutorialspoint;

// enum showing programming languages
enum Language {
   C, Java, PHP;
}
public class EnumDemo {
   public static void main(String args[]) {

      // returns the name and name of this enum constant
      System.out.print("Programming in " + Language.C.toString());      
      System.out.println(", Name = " + Language.C.name()); 
      System.out.print("Programming in " + Language.Java.toString());  
      System.out.println(", Name = " + Language.Java.name()); 
      System.out.print("Programming in " + Language.PHP.toString());  
      System.out.println(", Name = " + Language.PHP.name());    
   }
} 

输出

让我们编译并运行上述程序，这将产生以下结果：

Programming in C, Name = C
Programming in Java, Name = Java
Programming in PHP, Name = PHP

获取枚举名称示例

以下示例显示了不同枚举的 name() 方法的另一种用法。

package com.tutorialspoint;

// enum showing topics covered under Tutorials
enum Tutorials {  
   Java, HTML, Python; 
}  
public class EnumDemo { 
   public static void main(String args[]) {
      Tutorials t1, t2, t3;     
      t1 = Tutorials.Java; 
      t2 = Tutorials.HTML; 
      t3 = Tutorials.Python;     
      System.out.print("Programming in " + t1.toString());      
      System.out.println(", Name = " + t1.name()); 
      System.out.print("Programming in " + t2.toString());  
      System.out.println(", Name = " + t2.name()); 
      System.out.print("Programming in " + t3.toString());  
      System.out.println(", Name = " + t3.name());
   } 
} 

输出

让我们编译并运行上述程序，这将产生以下结果：

Programming in Java, Name = Java
Programming in HTML, Name = HTML
Programming in Python, Name = Python
