Question
Chapter 8.6, Problem 8.31CP
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.

Design a class nam
Start your trial
Design a class named MyPoint to represent a point with
X-and y-coordinates. The class contains:
The data fields x and y that represent the coordinates with getter methods.
A no-arg constructor that creates a point (0, 0).
A constructor that constructs a point with specified coordinates.
A method named distance that returns the distance from this point to a
specified point of the MyPoint type.
A method named distance that returns the distance from this point to
another point with specified x- and y-coordinates.
A static method named distance that returns the distance from two MyPoint
objects.
Draw the UML diagram for the class then implement the class. Write a test
program that creates the two points (0, 0) and (10, 30.5) and displays the distance
between them.
