String manipulation example (Title case)

[Java Tip]

Presented below is an interesting example of how you can change the case of a String into title case using simple string functions.

Code:

		String str = "MERCURY";
		str = str.toLowerCase();
		int intTmp = (int)str.charAt(0) - 32;
		
		char[] carray = str.toCharArray();
		carray[0] = (char)intTmp;
		
		str = String.valueOf(carray);
		System.out.println(str);
