Question

I have a String test="The Mountain view", i need all character after a space in a String need to be in Upper case , for example in the above text 'M' is uppercase after space, the condition need to be reflect for every character after space in String.

I need a regular expression or condition to check all character after space is in Upper case or else i need change the String after space into upper case character if it is in lower case.

If anyone knows means help me out.

There’s no need for regular expressions. Try this example, maybe helps:

public class Capitalize {

    public static String capitalize(String s) {
        if (s.length() == 0) return s;
        return s.substring(0, 1).toUpperCase() + s.substring(1).toLowerCase();
    }

    public static void main(String[] args) {
        while (!StdIn.isEmpty()) {
            String line = StdIn.readLine();
            String[] words = line.split("\\s");
            for (String s : words) {
                StdOut.print(capitalize(s) + " ");
            }
            StdOut.println();
        }
    }

}
