l have question regarading the answer for first question:

Modify your program from Assignment # 7 part b by creating an interactive GUI application that displays the list of the accounts read in from the file (create a text data file using your CreateBankFile.java program which has a least 10 bank account records in it and include it with your submission) and the total number of bank accounts. When your program starts it will first read the records from the Bank Account file and creates an array of BankAcct objects. The user of the application will then be able to have the bank accounts sorted (sorting the array of BankAcct objects) in the list by either, Customer #, Customer name, or Customer balance. Save your application as GUIBankAcctSorter.java.

The output from your program will look something like this:

Sample output follows:

When the application opens the user sees the above window displayed on the monitor. The JTextArea control has been filled with the records read in from the file and at the bottom it displays the total number of orders read from the file. The user can scroll the JTextArea control to see those records which are out of view. The following are a series of what the window should look like when the user interacts with the program causing specific events to occur.

When the user clicks on the Balance checkbox the records in the JTextArea control are sorted in ascending order by Balance.

l did finsh the code but some part off it l am not able to finsh it regardig sort in asednding cust , Balance, name becuase l am not get at it if the buble sort is asednding how to apply it to to GUl application and how to set the source slected and deslected . this code there are missing statemnt regarding the buble sort and selcted item as

could we apply this buble sort

for(a = 0; a < someNums.length -1; ++a) for(b =0, b < someNums.length -1; ++b)

{

temp = someNums[b];

someNums[b] = someNums[b+1]

someNums[b+1] = temp;

}

how to applly the sort for the cast the blance and the name
