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.
