   <item title="Open the Java perspective" dialog="false" skip="false" href="/org.eclipse.platform.doc.user/concepts/concepts-4.htm">
      <description>
         If you're not already in the Java perspective, in the main menu select <b>Window > Open Perspective > Java or click on the "Click to Perform" link below.
      </description>
      <command serialization="org.eclipse.ui.perspectives.showPerspective(org.eclipse.ui.perspectives.showPerspective.perspectiveId=org.eclipse.jdt.ui.JavaPerspective)" required="false" translate="">

   <item title="Create a Java project" dialog="true" skip="false" href="/org.eclipse.jdt.doc.user/concepts/concepts-3.htm">
      <description>
         Before creating a class, we need a project to put it in. In the main toolbar, click on the <b>New Java Project button, or click on the link below. Enter HelloWorld for the project name, then	click Finish.

      <command serialization="org.eclipse.ui.newWizard(newWizardId=org.eclipse.jdt.ui.wizards.JavaProjectWizard)" required="false" translate="">

   <item title="Create your HelloWorld class" dialog="true" skip="false" href="/org.eclipse.jdt.doc.user/gettingStarted/qs-9.htm">
      <description>
         The next step is to create a new class. In the main toolbar again, click on the <b>New Java Class button (or the link below). If not already specified, select HelloWorld/src as the source folder. Enter HelloWorld for the class name, select the checkbox to create the main() method, then click Finish.
<br/> The Java editor will automatically open showing your new class. </description> <command serialization="org.eclipse.ui.newWizard(newWizardId=org.eclipse.jdt.ui.wizards.NewClassCreationWizard)" required="false" translate=""> </command> </item> <item title="Add a print statement" dialog="false" skip="false" href="/org.eclipse.jdt.doc.user/concepts/concepts-7.htm"> <description> Now that you have your HelloWorld class, in the <b>main() method, add the following statement:
<br/> System.out.println("Hello world!");<br/> <br/> Then <b>save your changes; the class will automatically compile upon saving. </description> </item> <item title="Run your Java application" dialog="false" skip="false" href="/org.eclipse.jdt.doc.user/gettingStarted/qs-12.htm"> <description> To <b>run your application, right-click on your class in the Package Explorer and select Run As > Java Application. The Console view should appear at the bottom and display the "Hello, world!" output.
<br/> Congratulations! You have successfully created a Hello World application! </description> </item> </cheatsheet>
