Basic Syntax of Java

Even though the topics list covers everything that will be on the UIL CS Contest it is not in the order that you study. Here is an outline of topics that makes better sense.

• Arithmetic in binary, octal and hexadecimal
• Write the Hello World program
• Characterset - ASCII and Unicode
• Formation of variables
• Types - primitive types and reference types
• Statements and expressions
• Simple assignment statements
• Operators
• Arithmetic: +, -, *, /, %, ++, --
• Comparison: <, ≤, >, ≥, ==, !=
• Boolean: !, &&, ||
• Bitwise: &, |, ~, ^
• Shift: <<, >>, >>>
• Conditionals: if-else, switch
• Loops: while, for, do-while, foreach
• Methods: built-in, library, user-defined
• Libraries: math, string, random
• Arrays: 1-D and 2-D
• Input / Output: console, files

Here are some great sites to get started on programming:

• Coding Bat
• Geeks for Geeks
• Leet Code

Object Oriented Programming

There are four main principles in Object Oriented programming that you have to master:

• Abstraction
• Encapsulation
• Inheritance
• Polymorphism

• Object Oriented Programming Concepts
• Classes and Objects
• Interfaces and Inheritance

Now that you are aware of the basic syntax of Java download the current Topics List and study it very carefully. On the second page of the Topics list are the first 15 questions. These are questions that you must not miss. Note that the last two questions are free response questions.

Let us now work through some of the questions on the written portion of the UIL Contest.
