I figured most of it out but I need help with one thing -

In main I have



And in EmployeeDataReader I have:



How do I create an object like this:
Next you need to create a new Employee Object with the contents from the array of strings returned from split and store that into an array of Employee Objects. An initialized array of Employees will be returned to the caller.
The EmployeeData.csv file structure is: name,age,salary

Just Employee = new Employee(name, age, salary); ??

I just need to return an initialized array of employees but I'm not sure how to do this? Under double salary do I do Employee hello = new Employee (name, age, salary); ?? Then just return hello? But how do I do it as an array? Employee hello[]?

read through the file once to get the number of rows, then initialize the employee array with that size. Then use a counter to set the employees in the array to the new employee.

ex.

public Employee[] getEmployeeData(){
getFilePath();
/*Reads from the file stored in the attribute filePath. The file used is stored in
EmployeeData/EmployeeData.csv. A “csv” is a file structure that uses commas to
delimited values, thus the meaning comma separated values (csv). After you read a line
from the file use the split(“,”) string method, that will decompose the line into an array of
strings. Next you need to create a new Employee Object with the contents from the array of
strings returned from split and store that into an array of Employee Objects. An initialized
array of Employees will be returned to the caller.
The EmployeeData.csv file structure is: name,age,salary
Note: Check for overflow of your array, never trust that the number of lines in a file will be
the same size as your array! Make sure you use the int Integer.parseInt(String s) and
*/
try {


BufferedReader bufferedReader = new BufferedReader(new FileReader(filePath));
String input;
int count = 0;
while((input = bufferedReader.readLine()) != null)
{
count++;
}
bufferedReader .close();
Employee[] employees = new Employee[count];

BufferedReader data = new BufferedReader(new FileReader(filePath));

int i = 0;
while ((filePath = data.readLine()) != null) {

// use comma as separator
String[] dataz = line.split(",");
String name = dataz[0];
int age = Integer.parseInt(dataz[1]);
double salary = Double.parseDouble(dataz[2]);
employees[i]=new Employee(name,age,salary);
i++;
}

return employees;
}

What is the purpose of having the first while to count how many lines there are? I'm just wondering the logic behind it!

Thank you very much! I'll give it a try once I get rid of this stupid try statement that is messing it all up.

I did a sys.out line to see the count and it shows count == 12 when there's only 11 lines in the file.

I'm getting an Array out of bounds exception.

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1
at EmployeeDataReader.getEmployeeData(EmployeeDataReader.java:47)
at LabTwoDriver.main(LabTwoDriver.java:25)

LabTwoDriver 25 is where I call it all: Employee[] employeeDatabase = employeeDataReader.getEmployeeData();

Line 47 in EmployeeDataReader is where I parse the int: int age = Integer.parseInt(dataz[1]); Gives me index out of bounds??

e/ I'm not sure why it's throwing line 47 in DataReader I did system.out.print lines and it's printing the name/age correctly so I'm not exactly sure why there is an error.

look at where it's used. arrays are fixed structures; you need to know how many to put in it before you initialize the array. if you skipped the first loop, how would you know how many fit in the array?
