Question

Write a Java program that reads a list of 30 fruits from the file “fruits.txt”, inserts them into a string array, and sorts the array in alphabetical order. String objects can be compared using relational operators such as <, >, or ==. For example, “abc” > “abd” is false, but “abc” < “abd” is true. Sample output: Before Sorting: Cherry, Honeydew, Cranberry, Lemon, Orange, Persimmon, Watermelon, Kiwifruit, Lime, Pomegranate, Jujube, Pineapple, Durian, Plum, Banana, Coconut, Apple, Tomato, Raisin, Mandarine, Blackberry, Raspberry, Peach, Mango, Melon, Grape, Strawberry, Blueberry, Pear, Avocado After Sorting: Apple, Avocado, Banana, Blackberry, Blueberry, Cherry, Coconut, Cranberry, Durian, Grape, Honeydew, Jujube, Kiwifruit, Lemon, Lime, Mandarine, Mango, Melon, Orange, Peach, Pear, Persimmon, Pineapple, Plum, Pomegranate, Raisin, Raspberry, Strawberry, Tomato, Watermelon

Code:

=====

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;

public class SortFruits {
   public static void main(String[] args) throws FileNotFoundException {
       Scanner sc = new Scanner(new File("fruits.txt"));
       String[] fruits = new String[30];
       int i=0;
       while(sc.hasNextLine()) {
           fruits[i] = sc.nextLine().trim();
           i++;
       }
       System.out.println("Fruits before soring: ");
       for(String fruit : fruits) {
           System.out.print(fruit+", ");
       }
       String temp="";
       for(i=0; i<30; i++) {
           for(int j=0; j<30; j++) {
               if(fruits[i].compareTo(fruits[j])<0) {
                   temp = fruits[j];
                   fruits[j] = fruits[i];
                   fruits[i] = temp;
               }
           }
       }
       System.out.println("\n\nFruits after soring: ");
       for(String fruit : fruits) {
           System.out.print(fruit+", ");
       }
       sc.close();
