I need help writing and implementing a method containing a for loop.

PROMPT:

Step 1 - Write the listAll() Method

This method will cycle through all salaries in order. To allow reading to be easier, you should call prettyPrint(int) on every major. It is useful to know that calling data.size() will return the total number of majors that are being tracked in the salary data. If you have 27 majors, it will return 27, even though you should loop from 0 to 26.

Step 2 - Write the listAll() Method Signature

listAll() is a method that is public non-static that returns nothing and has no parameters. Dont forget your beginning and ending curly braces! It should look something like this:

public void listAll() 

When a method is non-static you do not include a static or non-static keyword after public.

Step 3 - Implement the listAll() Method

First, print out getHeader() with a new line so when you run listAll() the user will see a key to the info displayed. This will look like:

DataID. Major Avg. Male Salary Avg. Female Salary Avg. White Salary Avg. PoC Salary Salary Male % Female % White % PoC % 

Now, write a for loop to start at the beginning of our collection of elements called data, stop at the end of data and increments one at a time.

Collection of data is a new topic we are lightly introducing now (we will go over it more later) so to help you out data.size() will return the length of data. This return value is very similar to .length() for Strings. Keep in mind that length is not zero based so a collection of 5 elements will return 5, not 4 (the last index).

NOTE: data does not need to be re-declared since it is a class variable which can be used anywhere in the program with having to be passed as a parameter.

For each iteration of the for loop(inside the for loop) you will simply call prettyPrint() with your for loop variable as the parameter.

prettyPrint() takes an int that represents which individual salary the method will print to the console.
