ArrayList<String> fruits = new ArrayList<>();
Scanner sc = new Scanner(System.in);
String fruit = "?";
while (!fruit.isEmpty()) {
    
    // prompt the user to enter a fruit
    
    
    // read the fruit using "sc", saving it into variable "fruit"
    
    
    // convert the fruit entered to lowercase
    
    
    // if the fruit is NOT empty and it is a new fruit, add it to ArrayList "fruits"
    
}

// display all fruits

Answer 1

Java Program to read fruits into Array List and display them:

//importing packages

import java.util.ArrayList;
import java.util.Scanner;

public class Main
{
   public static void main(String[] args) {
  
   ArrayList<String> fruits = new ArrayList<>();
  
Scanner sc = new Scanner(System.in);
  
String fruit = " ";
  
while (!fruit.isEmpty()) {
  
   // prompt the user to enter a fruit
   System.out.println("Enter a fruit");

// read the fruit using "sc", saving it into variable "fruit"     
   fruit=sc.nextLine();
     
   // convert the fruit entered to lowercase
   fruit=fruit.toLowerCase();
     
   // if the fruit is NOT empty and it is a new fruit, add it to ArrayList "fruits"
   if(!fruits.contains(fruit) && !fruit.isEmpty()){
  
fruits.add(fruit);     
     
   }
     
   }
     
   System.out.println("Displaying Fruits : ");   
  

//Displaying Fruits
   for(int i = 0; i < fruits.size(); i++) {

System.out.print(fruits.get(i) + "\n");
  
   }
  
}
}
