Question

Class DemoArray: 1. Create an array of type String , name it words, and initialize it with the following words: one, two, three, four, five, four, three, two, one 2. Use a method of class Arrays to print the array. Make sure to use a label 3. At this point we are going to fix the misspelled word three. Use a loop to access the elements of the array. One by one check whether the current element happens to be three. If that is the case, assign the correctly spelled word three to that array element 4. Again print the result. This time there should be no rectangular brackets nor commas

Answer 1

Please find the required program along with the comments and output:

import java.util.Arrays;

class DemoArray{
    public static void main(String[] args) {

        String[] words = {"one", "two", "three", "four", "five", "four", "three", "two", "one"};    //initialize words array with the given words

        System.out.println("Array Contents Before: "+ Arrays.toString(words));  //print the array contents using Arrays class method

        for(int i=0; i<words.length; i++) { //iterate over each element in the words array
            if(words[i].contains("three"))  //check for misspelled word three
                words[i] = "three"; //set the correct word
        }

        System.out.print("\nArray Contents After : ");  //print after correction
        for(int i=0; i<words.length; i++) {
            System.out.print(words[i] + " ");
        }

    }
}
