• Installing java/JDK

  • Knowing the difference between JDK, JRE and JVM

  • java -version to verify

• Setting up the path

  • Setup JAVA_HOME, export JAVA_HOME=/<your_JDK_folder> for mac

    • for linus export JAVA_HOME=/usr/local/jdk

  • setup java and javac path: export PATH=$PATH:$JAVA_HOME/bin/

• Installing and setting up IDE (Intellij)

  • Can use Eclipse or Netbeans, but Intellij is far better

• Settings to use JDK

  • Create new project using maven and add java build in pom.xml

  • See for a common starter pom file https://github.com/hanfak/java-generics/blob/master/pom.xml

    • For options 'groupId' and 'artifactId' when asked, use a package structure like com. as groupId and name of project as artifactId.

• Running a simple hello world program through Intellij to check it is working

  public class Example {
      public static void main(String[] args) {
          System.out.println("Hello, World");
      }
  }
