    public static void main(String[] args) {
        String sample = "Java String endsWith example";
        System.out.println("Ends with 'e':   " + sample.endsWith("e"));   // true
        System.out.println("Ends with 'ple': " + sample.endsWith("ple")); // true
        System.out.println("Ends with 'Java':" + sample.endsWith("Java")); // false
    }
}
