( The BMI class ) Add the following new constructor in the BMI class:

/** Construct a BMI with the specified name, age, weight,
* feet, and inches
*/
public BMI(String name, int age, double weight, double feet,
double inches)

10.3

( The MyInteger class ) Design a class named MyInteger . The class contains:

An int data field named value that stores the int value represented by this
object.

■

A constructor that creates a MyInteger object for the specified int value.

■

A getter method that returns the int value.

■

The methods isEven() , isOdd() , and isPrime() that return true if the
value in this object is even, odd, or prime, respectively.

■

The static methods isEven(int) , isOdd(int) , and isPrime(int) that
return true if the specified value is even, odd, or prime, respectively.

■

The static methods isEven(MyInteger) , isOdd(MyInteger) , and
isPrime(MyInteger) that return true if the specified value is even, odd,
or prime, respectively.

■

The methods equals(int) and equals(MyInteger) that return true if
the value in this object is equal to the specified value.

■

A static method parseInt(char[]) that converts an array of numeric
characters to an int value.

■

A static method parseInt(String) that converts a string into an int
value.
Draw the UML diagram for the class and then implement the class. Write a cli-
ent program that tests all methods in the class.

( The MyPoint class ) 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.
Draw the UML diagram for the class and 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.

The MyPoint class

( Displaying the prime factors ) Write a program that prompts the user to enter
a positive integer and displays all its smallest factors in decreasing order. For
example, if the integer is 120 , the smallest factors are displayed as 5 , 3 , 2 , 2 ,
2 . Use the StackOfIntegers class to store the factors (e.g., 2 , 2 , 2 , 3 , 5 ) and
retrieve and display them in reverse order.

*10.6

( Displaying the prime numbers ) Write a program that displays all the prime
numbers less than 120 in decreasing order. Use the StackOfIntegers class
to store the prime numbers (e.g., 2 , 3 , 5 , ... ) and retrieve and display them in
reverse order.
