	{  
		char ch1 = 'N';  
		char ch2 = 'd';  
		char ch3 = '\u01f2';  
		char ch4  = '0';   
		char ch5  = '7';  

		boolean b1 = Character.isTitleCase(ch1);  
		boolean b2 = Character.isTitleCase(ch2);  
		boolean b3 = Character.isTitleCase(ch3);  
		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);  
		System.out.println(ch5 +" is title case character??:  "+b5);  
	}  
} 


N is title case character??: false
d is title case character??: false
? is title case character??: true
0 is title case character?? : false
