Question

In JAVA please,

Given any integer, print an English phrase that describes the integer (e.g. “One Thousand, Two Hundred Thirty Four”). An ArrayList must be used in your program.

Answer 1

Please let me know if anything is required.

Copyable code:

import java.io.*;
import java.util.*;

public class Main
{
   public static void main(String[] args) {
      
       ArrayList <String> engPhrase = new ArrayList <String>(19);
      
       //ArrayList to store the english Phrase for numbers
       engPhrase.add("Zero");
       engPhrase.add("One");
       engPhrase.add("Two");
       engPhrase.add("Three");
       engPhrase.add("Four");
       engPhrase.add("Five");
       engPhrase.add("Six");
       engPhrase.add("Seven");
       engPhrase.add("Eight");
       engPhrase.add("Nine");
       engPhrase.add("Ten");
      
       engPhrase.add("Twenty");
       engPhrase.add("Thirty");
       engPhrase.add("Fourty");
       engPhrase.add("Fifty");
       engPhrase.add("Sixty");
       engPhrase.add("Seventy");
       engPhrase.add("Eighty");
       engPhrase.add("Ninety");
      
       Scanner sc = new Scanner(System.in);
       System.out.print("Enter the number: "); //taking number input from the user
       int number = sc.nextInt();
       int temp = number;
      
       String strNumber = Integer.toString(number); //converting the number to string
      
       if(strNumber.length()==1) //if the number is of single digit
       {
       System.out.println(engPhrase.get(number));
       }
      
       else if(strNumber.length()==2) //if number is of two digits
       {
       //extracting the two digits from the number
       int ones= number%10;
       number=number/10;
       int tens= number%10;
      
       //printing the required results
       System.out.print(engPhrase.get(tens+9)+" ");
       if(ones!=0)
       System.out.print(engPhrase.get(ones)+" ");
       System.out.println("");
       }
      
       else if(strNumber.length()==3) //if number is of three digits
       {
       //extracting the three digits from the number
       int ones= number%10;
       number=number/10;
       int tens= number%10;
       number=number/10;
       int hundreds= number%10;
      
       //printing the required results
       System.out.print(engPhrase.get(hundreds)+" Hundred ");
       if(tens!=0)
       System.out.print(engPhrase.get(tens+9)+" ");
       if(ones!=0)
       System.out.print(engPhrase.get(ones)+" ");
       System.out.println("");
      
       }
      
       else if(strNumber.length()==4) //if number is of four digits
       {
       //extracting the four digits from the number
       int ones= number%10;
       number=number/10;
       int tens= number%10;
       number=number/10;
       int hundreds= number%10;
       number=number/10;
       int thousands= number%10;
      
       //printing the required results
       System.out.print(engPhrase.get(thousands)+" Thousand"+" ");
       if(hundreds!=0)
       System.out.print(engPhrase.get(hundreds)+" Hundred"+" ");
       if(tens!=0)
       System.out.print(engPhrase.get(tens+9)+" ");
       if(ones!=0)
       System.out.print(engPhrase.get(ones));
       System.out.println("");
       }
      
      
      
   }
}
