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 for tokenizing strings.
• The character that would separate tokens is termed as “delimiter”.
• The argument that is 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.
