Program code:

import java.util.*; public class IntegerName { /** Turns a number into its English name. @paran number a positive integer < 10,000 @return the name of the number(e.g. 'two hundred seventy four') **/ public static String intName(int number) { int part = number; // The part that still needs to be converted String name = ""; // The name of the number // ********* added newly ***************** // if the part is greater than 1000 if (part >= 1000) { // then get digit at 1000's place and get equivalent digit name and add a string "thousand" after it name = digitName(part / 1000) + " thousand "; // remove digit at thousands place part = part % 1000; } if (part >= 100) { name = name + digitName(part / 100) + " hundred"; part = part % 100; } if (part >= 20) { name = name + " " + tensName(part); part = part % 10; } else if (part >= 10) { name = name + " " + tensName(part); part = 0; } if (part > 0) { name = name + " " + digitName(part); } return name; } /** Turns a digit into its English name @param digit an integer between 1 and 9 @return the name f the digit ("one" ...

the above provided code is working fine for input 9999, but when the input is changed to 55555(5 -digit or higher number the results are not satisfatory. modify the intName method so that it works correctly for values < 1,000,000,000.

Sample output:

99999: ninety-nine thousand nine hundred ninety-nine

run2:

999999: nine hundred ninety-nine thousand nine hundred ninety-nine
