		int index = Collections.binarysearch (ls, "BCD");
		SOP ("Index:" + index);
		int index2 = Collections.binarysearch (ls, "bcde");
		SOP ("Index2:" + index2);
		Returns the index of the search key if the search key is included in the list, otherwise return (-(insertion point)-1)
	
		//replace 
		collections.replaceall (LS, AFS, KK);
		SOP (LS);

		Inversion, inverse
		collections.reverse (LS);
		SOP (LS);

		
		The Fill method converts all elements in the list collection to the specified element
		collections.fill (ls, "pp");
		SOP (LS);

	public static void Sop (Object obj)
	{
		System.out.println (obj);
