Review of Java:

Variables:

Types:

int - integer

char - character

String - holds words and sentences

double - holds floating point numbers (decimals)

Legal Names:

Must begin with a letter

Cannot have spaces

Only punctuation allowed is the underscore _

Naming Style (either is acceptable):

theName - squish everything together. First word starts with lower-case letter. Other words start with upper-case letters

the_name - everything is lower-case. Separate words with underscore _

Assigning a Value

int num = 5;

double num2 = 3.4;

String word = "Cat"; (Notice the double quotes)

char letter = 'a'; (Notice the single quotes)

Operators:

+ Addition

- Subtraction

* Multiplication

/ Division

% Modulus (Finds the remainder. 7%4 = 3)

++ Adds one to the preceding variable. For example int num = 3; num++; Now num equals 4.

-- Subtracts one from the preceding variable.

+= Adds the value to the preceding varialbe. For example int num =3; num+=4; Now num equals 7.

-= Subtracts the value from the preceding variable.

Input:

import java.util.*;

import java.io.*;

Scanner myScan = new Scanner(System.in);

int num = myScan.nextInt(); //A nextLine() should follow EVERY nextInt.

myScan.nextLine();

Boolean Expressions:

< Less Than

> Greater Than

>= Greater Than or Equal To

<= Less Than or Equal To

= Assign a value to a variable. For example, num=3.

== Compares two values. For Example, if (num == 3).

! Not. For Example, if (!available())

!= Not Equal. For Example, if (num != num2)

&& And

|| Or

A B A && B A || B !B

T T T T F

T F F T T

F T F T

F F F F

If Statement:

Requires curly braces following it if there is more than one line of code. For Example:

if (true)

return true; //This is legal.

---------------------------------------

if (true)

isAvailable();

return true; //This is the same as below.

if (true)

{

isAvailable();

}

return true;

If statements do not have to have an else statement

For Loop:

for(initial; condition; update)

{

code

}

Example:

for (int i=0; i<10; i++)

{

System.out.print("*");

}

//This prints 10 stars - **********

Arrays:

Declare an array: int numbers[] = new int[100];

numbers[0] = 7; //first element is set to 7 (arrays start at 0)

numbers[100] = 56; //NOT LEGAL! The last index of the array is 99.

Use a loop to access the array.

for(int i=0; i<100; i++)

{

System.out.print("Enter a number: ");

numbers[i] = myScan.nextInt(); //i is used to index into the array

} //This loop allows the user to enter 100 numbers.

Hangman

Create a hangman game. Let the computer pick (randomly) a word from a string array and let the user guess that word. Count the right and wrong guesses. Let the user lose if it took him more than 5 wrong guesses.

Challenge

Create and update a picture of the hangman using ASCII Art

1. int [ ] nums = new int [20];//creates an array called nums that holds 20 nums with indexes from 0 to 19
2. int [ ] nums = {0, 4, 9,15, 42, -6, 2};

Length
1. int len = nums.length; //sets an int variable called len to equal the length of the nums array

Access an array slot
1. nums[5] = 15; //stores 15 in the 5 slot of the array
2. if (nums[5]==4) //an if statement to see if the value in slot 5 equals 4

Access the first slot of an array
1. nums[0] //slot 0 is always the first in an array

Access the last slot of an array
1. nums[nums.length-1] //the last slot of an array is always at the length - 1 because the slots start counting at 0 instead of 1
