Question

Can anyone please help me on how to convert words into numbers in java programming, using string tokenizer. Your answer will be highly appreciated. for example four hundred four should be 404 ... thanks alot

Answer 1

I'm guessing this is homework. The basic strategy would be to have a value variable that you work with. Each time you see a string "one", "two", "eleven", "seventy" you would add that amount to value. When you see a string like "hundred", "thousand", "million", you would multiply value by that amount.

For larger numbers you'll probably need to create a few subtotals and combine at the end. The steps to process a number like 111,374 written out as "one hundred eleven thousand three hundred seventy four" would be

• "one" -> value[0] += 1 (now 1)
• "hundred" -> value[0] *= 100 (now 100)
• "eleven" -> value[0] += 11 (now 111)
• "thousand" -> value[0] *= 1000 (now 111000)
• "three" -> value[1] += 3
• "hundred" -> value[1] *= 100 (now 300)
• "seventy" -> value[1] += 70 (now 370)
• "four" -> value[1] += 4 now (374)

You'll still need to figure out how to decide when to build it as multiple values.
