Question

I’ve looked all over for how to capitalize the first character of a string, but nothing I’ve found has helped. For my method to work, I need to set a user entered string to lower case.

sourceText = enterText.getText();
char chr = sourceText.charAt(0);

so I have a boolean that’s true if the first character is uppercase.

boolean upperCase = Character.isUpperCase(chr);
sourceTextLower = sourceText.toLowerCase();

Cool stuff happens here, and the final product is another string called translatedTextString and an if statement

String s2 = "";
if(upperCase == true)
{
    int x = translatedTextString.length();
    s2 = translatedTextString.substring(0,1).toUpperCase().concat(translatedTextString.substring(1, x));
}

//translatedText is a label
translatedText.setText(s2);

However, when I run the program, the first character of my result is still lower case. So my questions is: is this even the right way to go about doing this? If so, what am I doing wrong, and if not, how can I do it correctly?

It might be easier just to assume that the first letter is always lowercase, then you don’t need any checks:

String s         = "some string";
String capitol   = Character.toString(s.charAt(0)).toUpperCase();
String newString = capitol + s.substring(1,x);
