The triangle game is a pencil and paper game.
The game board is as follows:
O
O O
O O O
O O O O
O O O O O
O O O O O O
Conditional statements allow the program to go in different directions. They are like the choose-your-own adventure books you might have read as a child.
if (condition1)
statement1;
else if (condition2)
statement2;
else
statement3;
In the above if structure if condition1 is true then statement1 is executed. If condition2 is true then statement2 is executed. Otherwise if neither condition1 nor condition2 is true statement3 is executed.
For example:
if (x == 3)
x=6;
else if (x < 7)
x=5;
else
x=3;
Logically the above code reads as follows:
If x is equal to three x is assigned the value 6.
If x is not three but is any other number that is less then 7 then x is assigned the value 5.
Otherwise if x is neither equal to 3 or less than 7 then x is assigned the value 3.

Important Non-primative Types
There are three basic types of loops in Java: the for loop, the while loop, and the do loop. Each type is explained below.
