	    		return "A grape is a non-climacteric fruit.";
	    	}
	    }, 
	    APPLE{
	    	public String toString(){
	    		return "The apple is the pomaceous fruit.";
	    	}
	    }, 
	    MANGO{
	    	public String toString(){
	    		return "The mango is a fleshy stone fruit.";
	    	}
	    }, 
	    LEMON{
	    	public String toString(){
	    		return "Lemons are slow growing varieties of citrus.";
	    	}
	    } 
	}
	
	public static void main(String a[]){
		System.out.println(Fruit.GRAPE);
