Introduction to Java

Install JDK:

brew tap caskroom/cask
brew install brew-cask
brew cask install java

Run in the terminal the following command:

javac -version

You should see something like:

javac 1.8.0_91

In the terminal run the following commands:

mkdir java-trainning
cd java-trainning
wget https://goo.gl/6sJFwF -O HelloWorld.java
javac HelloWorld.java
java HelloWorld

You should see the following message:

Hello World

If running the command wget https://goo.gl/6sJFwF -O HelloWorld.java you get the message: bash: wget: command not found run the following command to install wget
```
brew install wget
```

And what about when the "brew" command is not found? :-)
