Lab Hanoi Tower

The pseudocode for Hanoi Tower is as follows:

solve(N, Src, Aux, Dst)
if N is 0 return
solve(N-1, Src, Dst, Aux)
Move N from Src to Dst
solve(N-1, Aux, Src, Dst)


Write the Java program based on the pseudocode in the above.

Lab Factorial

Write a Java program that computes N! where N is a positive integer.

Hint:

public static long factorial(int n)

Lab Recursive Method

Write a recursive method to compute Fibonacci series.

Hint:

1.
fib(n)=fib(n-1)+fib(n-2)

2.
public static long fib(int n)

StaticMethod

Define a Complex class with a static method for computing complex addition. Use (2+3i)+(4+5i) in your test.

Constructor

Overloading

Lab ADT

Define a Complex class and write an object oriented program to compute (2+3i)+(4+5i) in Java.
The methods should include an access and a mutator.

lab Fraction equality test

Write a program to implement a method that can check whether 2 fractions are equal. You will implement a class called Fraction consisting of a numerator and a denominator. The equality test of 2 fractions should return a boolean value.

Use the following as the tests.

* 1/2, 2/4
* 5/6, 6/7


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

lab Fraction Addition

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);

Homework 10-24-2008

1. Write a program to generate the series 1, 1, 2, 3, 5, 8, 13, ...
The series has a property that the third number is the sum of the first and second numbers. For example, 2=1+1, 3=1+2, and 5=2+3.



2. Write a program to generate the following table of arithmetic expressions

1*1=1 1*2=2 1*3=3 ... 1*9=9
2*1=2 2*2=4 2*3=6 ... 2*9=19
...
9*1=9 9*2=18 9*3=27 ... 9*9=81

Lab Finding the max of a list of numbers

Based on your study of Display 3.8, write a code to find the max and min of a list of number.
For example, given 1,3,5, and9, the max is 9 and the min is 1.
Your program should be able to process a list of any length.

Lab Finding the max of three numbers

Write a program to decide the max number of the three input number.

Lab Keyboard Input

Rewrite Display 2.6 using BufferedReader.

You need to import the following packages in the first place.

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.IOException;

Change

Scanner keyboard= new Scanner(System.in);

into

BufferedReader keyboard= new BufferedReader(new InputStreamReader(System.in));

String inputString = keyboard.readLine();

Note the Main method needs IOException handling as follows:

public static void main (String[] args) throws IOException
