Standard way to find a Character TYPE!

While we are processing Characters, it’s a very common practice that we use ASCII values…

I still remember in my computer class if I had to find out a character is a capital letter or not I would compare it with its ASCII value Sad smile 

I have also seen these comparisons Sad smile

if (ch >= ‘a’ && ch <= ‘z’ || ch >= ‘A’ && ch <= ‘Z’) – This means our character is an ALPHABET Sad smile

if (ch == ‘ ’) – This means our character is a whitespace Sad smile 

 

Now this comparison is language specific…I mean it works for English and some other international languages but fails for others…

If you are interested in having an internationally accepted Character Test Code ready then read on Smile 

 

Char cTest;

If (Character.isLetter(cTest) – This mean cTest is an Alphabet

If (Character.isDigit(cTest) – This mean cTest is a Digit

If (Character.isSpaceChar(cTest) – This mean cTest is a Space

 

There is a very useful function called getType which can return meaningful constants which will tell you the type of the character

if (Character.getType('s') == Character.LOWERCASE_LETTER) -  Lower Case Letter

if (Character.getType('_') == Character.CONNECTOR_PUNCTUATION)

 

Enjoy!!!!
