Lab Sorting

Study Display 6.1, and then write a program that can sort numbers in ascending order.

sample code of a class with static methods

public class RoundStuff
{
public static final double PI=3.14159;

public static double area(double radius)
{
return (PI*radius*radius);
}

public static double volume(double radius)
{
return((4.0/3.0)*PI*radius*radius*radius);
}
}

Lab Static Method, Part II

(1st ed.) Do Project 3 of Chap 5. Define a Complex class and write a program to compute (2+3i)+(4+5i) in Java.
(2nd ed.) Do Project 7 of Chap 5. Define a Complex class and write a program to compute (2+3i)+(4+5i) in Java.

Note:
Implement a static method and a nonstatic method using overloading. The results of these two methods should be the same.

Lab Static Method

Study Display 5.2.
Using static variables and static methods to implement the class Fibonacci such that
the first call to Fibonacci.next()
returns 2, the second returns 3, and then 5, and so on.

隨堂上機考 (2)

Write a program to implement a method that can do additions of 2 fractions. You will implement a class called Fraction consisting of a numerator and a denominator. The additions of
2 fractions should be equal to a fraction.
Use 1/2+1/3 as the test.

Hints:
Fraction f1, f2;
f1.add(f2);

隨堂上機考 (1)

Define a class called Counter whose objects count things. An object of this class records a count that is a nonnegative integer. Include methods to set the counter to 0, to increase the count by 1, and to decrease the count by 1. Include an accessor method that returns the current count value and a method that outputs the count to the screen. Write a program to test counter.reset(); counter.inc(); counter.inc(); counter.dec(); counter.output();
