converting to upper and lower case in java

Question

I want to convert the first character of a string into the upper case and the rest of the characters of the string into the lower case. How can I do this?

Answer 1

You can try this:

public class Main

{

public static String Convertoupperandlower(String s){

    if(s.length()==0)

    return "";

    else if(s.length()==1)

    return s.toUpperCase();

    return s.substring(0,1).toUpperCase()+s.substring(1).toLowerCase();

}

public static void main(String[] args) {

String s="bangalore";

System.out.println(Convertoupperandlower(s));

}

}
