How to capitalize the first letter of a String in Java?

Question

I am using Java to get string input from the user. I want to make the first letter of this input capitalized.

Can somebody help me with this?

Answer 1

You can use .substring() and .toUpperCase() like this:

public static void main(String[] args) throws IOException {

    BufferedReader bufferedreader = new BufferedReader(new InputStreamReader(System.in));

    // Actually use the Reader

    String name = bufferedreader.readLine();

    // Don't mistake String object with a Character object

    String s1 = name.substring(0, 1).toUpperCase();

    String nameCapitalized = s1 + name.substring(1);

    System.out.println(nameCapitalized);

}
