How To Brew Fresh Java For Tired Team Members

Pour the water in the reservoir and put the carafe on the heating plate. Measure Your Grounds: Add the desired amount of grounds to the filter: about 1 tablespoon per 5 to 6 fluid

unces of cold water for regular coffee, and 2

tablespoons per 5 to 6 fluid ounces for strong coffee.

Good Programming Habits

Use proper syntax
Keep similar programming styles
Make things easier to manage
Don’t trip on wires
Stick to your deadlines

SLIDE 7

What is Java?

Java is an object orientated programming language that was designed for the distributed environment of the internet.

SLIDE 8

Java Programming Platforms

Eclipse

○ Used for day to day coding. ○ Very versatile. ○ Industry standard.

Android Studio

○ Used for the programming of apps. ○ Used by Prior Lake Robotics FTC teams.

Netbeans

○ For developing desktop, mobile, and web applications. ○ Uses Java, Javascript, HTML5, PHP, C/C++, and more.

Classes

A class is a collection of related properties and behaviors, A class contains fields and methods (We will talk about these later) to describe the behavior of an object

SLIDE 10

Basic Layout - Hello World

Prints “Hello World” to the console. ← Class ← Main Method

SLIDE 11

Comments

← Single Line ← Multi-line

SLIDE 12

Variables

declaring initializing

SLIDE 13

Primitive data types

int - an integer or whole number 12 , 2169 , 1234 double - a decimal 2.22 , .25 , 1.1 boolean true or false char or character - holds a single letter or integers ‘A’ , ‘b’ , 2 , 45

Primitive data is data type provided by your program as simple building blocks.

SLIDE 14

Non-Primitive data types

Non-primitive data types are not defined by the programming language

SLIDE 15

Concatenation

To attach strings and variables together with the plus symbol

SLIDE 16

Boolean Expressions

ints , doubles , booleans , and chars Strings Boolean expression is a statement that compares all data typed and returns a true

r false.
Ex. if(3 > 2) it will return true

SLIDE 17

If and If-else statements

← boolean expression

SLIDE 18

If and If-else statements

Output to Console

SLIDE 21

Loops

All loops in java require three things…

An initialized value
An increment
And a stopping value

SLIDE 22

Increments and Decrements

Increase by 1 Decrease by 1
