#Control Structures

##If statement

Kotlin if statement should look familiar with other language

fun main(args : Array<String>) {
 val total = 10

This is a quick guide to Kotlin programming language. The previous part of this guide is here

#Object Oriented

fun main(args : Array<String>) {
  class local (val x : Int)
  
  val y = local(10)
 println("${y.x}")

#Intro

Kotlin is a new programming language for the JVM. It produces Java bytecode, supports Android and generates JavaScript. The latest version of the language is Kotlin M5.3

All the codes here can be copied and run on Kotlin online editor.

Let's get started.

public class Car {
    private Engine engine;
    private FuelTank fuelTank;

    public Car(Engine engine, FuelTank fuelTank) {
        this.engine = engine;
        this.fuelTank = fuelTank;
    }

    public void start() {

Oracle

Run for example docker image

Jboss configuration

As first create model directory and add module.xml

$ mkdir -p server/jboss-as-7.2.0.Final/modules/com/oracle/jdbc/ojdbc14/main/ $ vim server/jboss-as-7.2.0.Final/modules/com/oracle/jdbc/ojdbc14/main/module.xml

Could look like this:

## Register driver
ARCHIVE_NAME=ojdbc6.jar
REPOSITORY_DIR=pathToDriver
SERVER_DIR=pathToWildfly
INSTALL_DIR=$SERVER_DIR/modules/system/layers/base/com/oracle/ojdbc6/main
SERVER_USER=petr
SERVER_PASSW=petr

mkdir -p $INSTALL_DIR
cp $REPOSITORY_DIR/$ARCHIVE_NAME $INSTALL_DIR
