Program Plan Intro

Tokenizing Strings:

  • The tokenizing of a string denotes a process of dividing a string into its components termed as tokens.
  • The “split” method of “String” class could be used to tokenize strings.
  • The character that would separate tokens is termed as “delimiter”.
  • The argument passed to “split” method denotes a regular expression.
  • A regular expression is used to search for patterns in strings, files and other texts.
  • To prevent leading or trailing whitespace characters in tokens, the string is been trimmed.
  • The “trim” method of “String” class is been used for trimming purposes.

Wrapper class:

  • The wrapper class is been provided by Java API for numeric data types.
  • These classes contain methods that perform useful operations.
  • It involves primitive numeric values.
  • The static “toString” method converts to a string from a number.
    • The method that accepts number as its argument.
    • It returns a number’s string representation.
    • The “toBinaryString”, “toHexString”, and “toOctalString” accepts integer as argument.
      • It returns string representation of number converted into binary, hexadecimal and octal.
    • The “MAX_VALUE” and “MIN_VALUE” stores maximum and minimum value for a specific data type.
  • The “Autoboxing” denotes a java process for automatically boxing up a value inside an object.
  • The “Unboxing” denotes a reverse process of boxing; it converts a wrapper class object into a primitive type.

The assignment here is to write an app using a database named CIT321 with a collection named students; we will provide a CSV file of the data. You need to use Vue.js to display 2 pages. You should know that this assignment is similar, all too similar in fact, to the cars4sale2 example in the lecture notes for Vue.js 2. You should study that program first. If you figure out cars4sale2, then program 6 will be extremely straightforward. It is not my intent do drop a ton of new material here in the last few days of class. The database contains 51 documents. The first rows of the CSV file look like this: sid last_name 1 Astaire first_name Humphrey CIT major hrs_attempted gpa_points 10 34 2 Bacall Katharine EET 40 128 3 Bergman Bette EET 42 97 4 Bogart Cary CIT 11 33 5 Brando James WEB 59 183 6 Cagney Marlon CIT 13 40 GPA is calculated as gpa_points divided by hrs_attempted. GPA points would have been arrived at by adding 4 points for each credit hour of A, 3 points for each credit hour of…
