Question

Hey, I'm stuck on this assignment for AP Comp Sci Java. I don't know how to start.

An array of String objects, words, has been properly declared and initialized. Each element of words contains a String consisting of lowercase letters (a–z).

Write a code segment that uses an enhanced for loop to print all elements of words that end with "ing". As an example, if words contains {"ten", "fading", "post", "card", "thunder", "hinge", "trailing", "batting"}, then the following output should be produced by the code segment.

fading

trailing

batting

Answer 1

public class JavaApplication20 {

    public static void main(String[] args) {

        //initialize array

        String words[] = {"ten", "fading", "post", "card", "thunder", "hinge", "trailing", "batting"};

        //enhanced for loop to loop through the array

        for (String word : words) {

            //lastIndexOf() method returns the position of the last found occurrence

            //of the substring specified in a string

            if (word.lastIndexOf("ing") == word.length() - 3) {

                System.out.println(word);

            }

        }

    }

}
