		boolean b4 = Character.isTitleCase(ch4);  
		boolean b5 = Character.isTitleCase(ch5);  

		System.out.println(ch1 +" is title case character??:  "+b1);  
		System.out.println(ch2 +" is title case character??:  "+b2);  
		System.out.println(ch3 +" is title case character??:  "+b3);  
		System.out.println(ch4 +" is title case character?? : "+b4);
