Program:

            /* ............... START ............... */
                
public class JavaStringCaseOfCharacter {

	public static void main(String[] args) {
		String characters = "[email protected]%*765";
		int length = characters.length();
		for (int i = 0; i < length; i++) {
			char character = characters.charAt(i);
			if (Character.isUpperCase(character)) {
				System.out.println("Given character : " + characters.charAt(i) + " is an Uppercase letter");
			} else if (Character.isLowerCase(character)) {
				System.out.println("Given character : " + characters.charAt(i) + " is a Lowercase letter");
			} else {
				System.out.println(
						"Given character : " + characters.charAt(i) + " is neither Uppercase nor Lowercase letter");
			}
		}

	}
}
                /* ............... END ............... */
