Using Netbeans, write the two following exercises:

1 - Make a public class called ReadAccount. This class will read a file ("accountsData.txt") where the data is "Byte-based stream." After reading the file should print the total sum of blanaces. The data should be read into an array. (Use AccountRecord class).

2 - Make a public class called WritenAccounts. This class will write to a file ("accountData.txt") where the data is "Byte-based stream." The program should ask several accounts and save the data in an array, to indicate that it is the end, then save each record or array in a file. (Use AccountRecord class).
