Lab Assignment 1: Due
to be marked in your scheduled lab time, week of January 24, 2005
The aim of this assignment is to
familiarize you with the Java environment and to introduce you to using predefined
classes.
- Design and implement an application called Hello.java which prints the phrase “Hello CSI
1102, Winter 2005!!!” on one line and the phrase
“Enjoy the course and have fun!” on another line. [3 marks]
- Design and implement an application Password.java
that produces and prints a random password. The password is composed of
random digits 0-9 and characters a-z. The first element is a character, the second is a digit, then a character, a
digit, a character, a digit, a character, and a digit (8 elements in
total). An example is: e5c8a0b6.
[7 marks]
- Design and implement an application Current.java
that computes the intensity of the electrical current in a resistor of
resistance R, when the applied voltage is V. Ask the user to input the
value of R (in ohms) and the values of V (in volts). Then print the value
of the intensity I, computed with the
formula I = V / R. Ask the user if she/he wants to repeat the
process, and allow it repeatedly while the answer is “y” or “Y”. This
question will familiarize you with reading input from the keyboard, using the
class cs1.Keyboard provided by the authors of the textbook. (Don’t forget
to run your program with Run with console instead of Run application.) [9 marks]
- Design and implement an application called MonsterGame.java
that simulates a simple game. You
have three magic arrows to kill an evil monster. When you fire an arrow,
the program generates a random integer between 0 and 10 (including 0 and
10). This number shows how much
damage you did to the monster. The monster has 10 energy points initially.
After each arrow is fired (by simply printing a message that says it was
fired and shows the random number), the monster’s energy is decreased by
the generated number (but not decreased below zero). After you fire the
first arrow, if the monster’s energy is zero, print the message “You
won!!!”; otherwise you fire the second arrow. After
you fire the second arrow, if the monster’s energy is zero, you win;
otherwise you fire the third arrow. If in the end the energy is zero, you
win; otherwise, print the message: “Nice try. Almost there!”. After each arrow is fired, print a message with the
current energy level left for the monster. After the game is over, print
the message “Do you want to play again? (y/n)”, and allow the user to play
as many times as desired. [11 marks]
