Java application: convert a floating point to an upper-case Chinese amount

Read a floating point value and convert it to the Chinese capital of the amount.

 

Test requirements:

 

When the amount is an integer, it only indicates the integer part, omitting the fractional part, and adding the word "integer.

 

When the amount contains 0 consecutive values, you only need one zero value.

 

The representation of 10. For example, 110 -- one yuan a collection, 10 --- one yuan a collection
