Create a 2D game engine that is fully functional using Java

Goals

• Complete Variables and Expressions Section

Numbers and variables are able to be stored inside letters. a = 1

The double code can be used to store numbers such as 10.5. double a; a = 10.5;

a = (int)10.5 the result will be 10.

E is used to show scientific notation. 5 x 10⁶ = 5E6

j++; = add j to the current value and then assign the new value to j.

Strings used similar to other programming languages. String s; string s = ḧello world

the length is the length of the string. use of / for escape characters.

System.out.println is a method that takes a single argument. When that argument is a string, then the contents of the string are displayed.

Going through boolean and arrays. Assign values with arrays. Everything can go together and can be combined.

• Complete Program Control Section

the use of if and else

different type of errors; symbols,incompatible types

it is important that at some point the loop condition should be false, so the execution of the loop body will stop. If the loop condition is always true, execution of the body will be repeated forever.

while and for

for loops that are designed specifically for situations in which the body of the loop is to be executed a number of times that is known in advance.
