Question

I'm still fairly new to java and I haven't programmed with it in half a year, so I can't for the life of me figure this out even though I know its really simple. I'll paste the 2 classes below so any help is much appreciated. The TODO comments are what I'm supposed to do.

public class Main
{
public static void main(String[] args)
{
/*
* This is for the first part of the lab.
*/
  
Planner coursePlan = new Planner("cs2334,Dale Hall,100");
System.out.println(coursePlan);
}
}

public class Planner
{
/*
* The maximum number of students that may be enrolled in a single section.
* Use this and the number of students enrolled in the class to calculate
* then number of sections needed for the class.
*/
private static final int MAX_SECTION_SIZE = 20;

/*
* This stores the data for the class in the following order:
* info[0] = class name (capitalized)
* info[1] = class location
* info[2] = number of students
* info[3] = number of sections needed
*/
private String[] info;

/**
* Constructor for Planning class. The constructor takes in an input
* string, breaks it up, and then stores the pieces into the class
* variable info. It also does a minor calculation to fill in info[3].
*
* The class name must be capitalized when it is stored.
* The number of sections is equal to the ceiling of (NumStudents/MAX_CLASS_SIZE)
*
* @param input A String containing information about the class. The input
* will always be String of 4 elements separated by commas of the form:
* "ClassName,ClassLocation,NumStudents"
*/
public Planner(String input)
{
//TODO: split input (look at String.split()) and store necessary information in the info array.
}

/**
* Getter method for the info array.
* @return information
*/
public String[] getInfo()
{
// TODO: return info array
}

/**
* This is the toString method. It overrides the default toString method
* to print out the information in the desired format.
*
* @return The string representation of the Planning object. The string is of the
* format:
* "CLASS: (className), LOCATION: (classLocation), ENROLLED: (numberStudents), SECTIONS: (numberSections)"
* Replace the parenthesized section with the stored values. e.g.
* if the class name is "CS2334", the first part of the string is "CLASS: CS2334"
* Make sure that all spaces and punctation are replicated exactly.
*/
@Override
public String toString()
{
//TODO: construct and return correct string.
}
}

Hey,

Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries

Kindly revert for any queries

Thanks.
