Question

This is java

In this program, you are going to read in a top 50 women in business data set file, Top50.txt. You are going to create a BusinessWoman object which keeps track of the ID, FirstName, LastName, CompanyName, and Age.

You are going to store it into an array of BusinessWoman objects. The default starting size is 10. You are going mimic an ArrayList, and when you add items you will use an add method that you create. If you run out of space, you need to expand the array (double its size) and copy all the previous items into the new array when you run out of space.
Finally, you should print out each of the objects by using a get method that you create. Specifics:

1. Read in the Top50 file and create BusinessWoman objects. 2. Store each object into the array you created. 3. Initialize the array size to 10. Please do not use an actual ArrayList. 4. Create an expand method when the number of items read in exceeds the size of the array. 5. Create a size method to keep track of how large your "ArrayList. " 6. Create an add method to add items to your "ArrayList. " 7. Create a get method to get items out of your "ArrayList.” 8. Print out all the students in your "ArrayList" at the end.

Top50.txt.
