Hey everyone,

I'm new at this.. so please bear with me.

Anyway, I'm really confused.

I'm supposed to convert the first character of the String firstName to upper case.

Problem is... I have no idea how to

I've done so much research and reading and still nothing.

Please help me.

Thanks in advance!

This is my code;

public class Main {

/**
* @param args the command line arguments
*/
public static void main(String[] args) {

char firstSymbol;


// First and Last Name

String firstName="mickey";
String lastName="mouse";
System.out.println(lastName + "," + firstName);

Check out the java API: http://java.sun.com/j2se/1.4.2/docs/...Character.html

If you still can't figure it out let me know.

Thank you for your reply.
I figured out how to do it using the replace method. However, now I'm asked to do it using the variable firstSymbol.

Well if you use the replace method you will have to hard code your code. Which is ok if you know what the string variable contains, In a case where you don't know, this will not be good. So It is probably good if you get familiar with the toUpperCase method in the Character class.

Here is an example how to use it:

Thank you! Works great, But does it incorporate the firstSymbol variable I told you about? =/

Have you heard of unicode? In unicode each character has a corresponding number. A-Z corresponds with 65-90, while a-z corresponds with 97-122. In order to make the letter j into a capitol J you would convert the j into unicode, subtract 22, and convert back to letters, but I don't remember how to do it and I forgot to write it down in my notes LOL so just search around for unicode and it should help you.

PS I am a student and I just learned about this last week so if I'm wrong please feel free to correct me... I am trying to solve my own problems and thought I'd look around and see what else was here lol

Hi guys, converting uppercase or lowercase strings in java is so simple but if you wanna see a more complex application you can look at here...

There is a function that makes first letters of words, sentences or lines Uppercased in JAVA.

This may be useful for learning more string operations.
