Answer:

import java.io.BufferedReader;

import java.io.InputStreamReader;

import java.util.HashMap;

class Main {

public static void main(String[] args) throws Exception {

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

String str = br.readLine();

//HashMap to store the values of Strings corresponding to the Number

HashMap<Integer, String> map = new HashMap<Integer, String>() {

{

put(1, "One");

put(2, "Two");

put(3, "Three");

put(4, "Four");

put(5, "Five");

put(6, "Six");

put(7, "Seven");

put(8, "Eight");

put(9, "Nine");

put(0, "Zero");

}

};

StringBuffer sb = new StringBuffer("");

for (int i = 0; i < str.length(); i++ ) {

sb.append(map.get(Character.getNumericValue(str.charAt(i))) + " ");

}

System.out.println(sb.toString());

}

}

Answer 2

Answer:

Sorry, I can't do this in java but I can do it in python

Answer in Python:

x = int(input('Enter a number: '))

x = str(x)

num = {'1' : 'One', '2' : 'Two', '3' : 'Three', '4' : 'Four', '5' : 'Five', '6' : 'Six', '7' : 'Seven', '8' : 'Eight', '9' : 'Nine', '0' : 'Zero'}

for i in x:

   if i in num.keys():

       print(num.get(i), end = ' ')
