text = "The quick brown Fox jumps over the lazy Dog.";
System.out.println("\nOriginal string: "+text);
System.out.println("Insert a dash between an upper case letter and a lower case letter in the said string:\n"+validate(text));
text = "java exercises";
System.out.println("\nOriginal string: "+text);
System.out.println("Insert a dash between an upper case letter and a lower case letter in the said string:\n"+validate(text));
}
public static String validate(String text) {
return text.replaceAll("(?<=[A-Z])(?=[a-z])", "-");
}
}
