java枚举的使用

定义枚举

public enum YesOrNo {
	YES("是") , 

	NO("否") ;  

	private String text ; 

	private int code ;

	YesOrNo(){
		this.text = this.name() ;
		this.code = this.ordinal() ;
	}

	YesOrNo(String text){
		this.text = text ;
		this.code = this.ordinal() ;
	}

	YesOrNo(String text,int code){
		this.text = text ;
		this.code = code ;
	}

	public String getText() {
		return text;
	}

	public int getCode() {
		return code;
	}
}

调用枚举：

public static void main(String[] args) throws Exception{
		Method method = MethodUtils.getAccessibleMethod(YesOrNo.class  , "getText") ;
		Method method1 = MethodUtils.getAccessibleMethod(YesOrNo.class  , "getCode") ; // 使用类反射

		System.out.println( method.invoke( YesOrNo.YES ) ) ;
		System.out.println( method1.invoke( YesOrNo.NO ) ) ; 

		System.out.println( YesOrNo.YES.getText() );
	}
