Introduction To Java (2-Day Class)

Java's motto is write once, run anywhere; code that runs on one platform need not be recompiled for a different platform. Older code runs on the most JVMs with the speed advantage of the latest profiling, native code translating, and memory management.

Prerequisites: No previous programming or Java background is required.   

A general-purpose, concurrent, class-based, object-oriented programming Language, Java is designed to be portable across different platforms. It tries to have as few implementation dependencies as possible. Java follows many of the syntactic conventions of C and C++.

The course will cover the syntax, data structures, common classes, and common techniques of Java programming. 

The course is set up in a lab-like environment. Students will learn Java by working through instructor-led exercises and examples that will introduce them to each new topic. 

Topics covered include: 

Basics

• Hello World program in Java
• Command-line compile using javac
• Command-line deployment using jar
• CLASSPATH

Basic Syntax

• Structure of program
• Comments
• Statements
• Assignments
• Calling methods on objects
• Calling methods on classes

Primitive Data Types

• Println statement
• Variables, types, assignment
• Numeric types: integer, floating-point
• Integer literals
• Floating-point literals
• Numeric operators: + / * % 
• Assignment operators, increment/decrement operators
• Relational operators: < > <= >= == !=
• Boolean type
• Boolean operators: && || !

Strings

• Character literals
• String literals
• Escaped characters: \n \t \\ \" \'
• String operators: + +=
• Accessing string characters
• String comparison and equality

Control Structures

• If, If-Else
