Chapter 8.6, Problem 8.30CP
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 separating 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.
