If you want see three random letter characters and three random number characters, why didn't you print them?

Array license contains your expected values. Print it.

Why are you using a Long?

Because: digit between 0 ≤ A ≤ 10X18, but Integer.MAX_VALUE=2147483647

Why are you putting Longs into a List?

Because I dont know how much digits came from input string. In this case where can I save any number od digits? In array? But How?

Why have you got a byte[]?

I uploaded code on http://acm.timus.ru/. On this server code was successfully executed and passed through couple tests. All happened automatically.

Sorry, could you please provide Actual and Expected results?

The input stream contains a set of integer numbers Ai (0 ≤ Ai ≤ 1018). The numbers are separated by any number of spaces and line breaks. A size of the input stream does not exceed 256 KB.
For each number Ai from the last one till the first one you should output its square root. Each square root should be printed in a separate line with at least four digits after decimal point.

My code below:

Judgement result:

So, my first goal was successfully completed - I found solution for this exercise.
but, currently, I think about other point: code quality.
I would like reach high code quality level.

What do you think, this code is ok? Because, I am not sure, that my solution with processing InputStream is really cool.
Could you please suggest any improvements if it is need.

but each method contains javadoc, and each javadoc section contains information about "throws Exceptions"

For example:


public ResultSet executeQuery(String sql)
throws SQLException
Executes the given SQL statement, which returns a single ResultSet object.
sql - an SQL statement to be sent to the database, typically a static SQL SELECT statement
a ResultSet object that contains the data produced by the given query; never null
SQLException - if a database access error occurs or the given SQL statement produces anything other than a single ResultSet object

Because, it is checked Exception.
but this is 9! results. (9*8*7*6*5*4*3*2=362880)

Is it ok?

After each step, you don't change coordinates, why?

I think it is a root of the issue.

Okay i get you now.
An yes i was running it like this: c:>java TestHomework

Is there any way i can make it so when i run it it will ask me what i put like "What is the name of the shuffled deck file? " and then enter the name of the file
instead if putting it along with the java TestHomework?

Of course you can do it. Take a look at this link, please: webpage
