// #4 decode number of classes from token, convert text to int--parseInt is an alternative to valueOf

// #5 Put the class names in an array of Strings from the right token

// Since classes are text, we can just split the string by commas

// and we're done with class names

// #6 Puts the class credits in an array of ints

// --First declare an array of ints to hold final converted data

// --use numClasses as size of array

// #6 continued We're going to need a temporary array to hold the

// text versions of the credits. Declare array and do split at same time.

// the split method will dimension the array

// #7 Follow same pattern to Convert the class credits information that are Strings into ints

// parseInt like valueOf converts a text into a real number

// #8 Put the class grades in an array like we did for credits

// First declare your array to hold the final double data

// Hint: reuse your temporary array to capture the comma-separated grades

// Convert the class grades strings into doubles

// #9 Now you have all the data needed to fully describe this instance of a Student

// Add class data to Student object using Student's public API (addClasses)

// #10 add your fully filled in Student object into your array of Students

// Hine use a counter to keep track of the current array index

}
