Question

Improve the intName method in IntegerName. java so that it can handle arguments up to 9999.

Answer 1

To handle numbers up to 9999 in the IntegerName.java method, add a layer to process the thousands place by converting the digit to its name, appending 'thousand', and then using existing logic for the remainder of the number.

Step-by-step explanation:

To improve the intName method in IntegerName.java to handle arguments up to 9999, we need to build on the existing logic that likely handles numbers up to 999. This involves adding another layer of decomposition to handle the thousands place. The method should first check if the number is greater than or equal to 1000, then it should handle the thousands place by finding the corresponding name for the thousands digit, appending 'thousand', and then processing the remainder of the number. Below is a step-by-step method that shows how you might improve the method:

• 
  
• Check if the number is between 1000 and 9999.
• 
  
• Extract the digit in the thousands place and find its name.
• 
  
• Append the word 'thousand' to the name of the thousands digit.
• 
  
• Process the remaining three digits as per the existing logic in the intName method.

Example:

For the input 2354, the method would break down the process as follows:

1. 
   
3. 2 is 'two' + 'thousand' = 'two thousand'
4. 
   
6. 354 is processed by the existing method (e.g., 'three hundred fifty-four')
7. 
   
9. The final output would be: 'two thousand three hundred fifty-four'
