Question

Write a program that stores a phrase as an array of words, and then prints it backwards. The main method calls method getInput , which asks the user how many words there are, stores them in an array, and returns this array. printBackwards then takes this array of words, and prints it in reverse.

Code Example:

import java.util.Scanner;
public class L17Num1{
  
public static void main(String[] args) {
  
String[] sArray=getInput();
printBackwards(sArray);

}
public static String[] getInput()
{
System.out.println("How many words are there?");
Scanner scnr = new Scanner(System.in);
int num=scnr.nextInt();
String[] words = new String[num];
for (int i=0;i<num;i++){
words[i] = scnr.nextLine();
}
return words;
}

public static void printBackwards(String []w)
{
for(int i=0;i<w.length;i++)
System.out.println(w[i]);
}
}

import java.util.Scanner;
public class L17Num1{

    public static void main(String[] args) {

        String[] sArray=getInput();
        printBackwards(sArray);

    }
    public static String[] getInput()
    {
        System.out.println("How many words are there?");
        Scanner scnr = new Scanner(System.in);
        int num=scnr.nextInt();
        String[] words = new String[num];
        System.out.print("Enter the phrase ");
        for (int i=0;i<num;i++){
            words[i] = scnr.next();
        }
        return words;
    }

    public static void printBackwards(String []w)
    {
        for(int i=w.length-1;i>=0;i--)
            System.out.println(w[i]);
    }
}
