How do i use netbeans

Right-click the AnagramGame project in the Projects window and select Properties from the context menu. Java SE 8 introduces subset profiles of the Java SE platform specification that can be used to deploy and run applications that do not require the entire platform. Three profiles that have been defined so far are named compact1 , compact2 , and compact3. Each profile specifies a particular set of Java API packages and contains all of the APIs in profiles smaller than itself: compact1 is a subset of compact2 , which is a subset of compact3 , which in its turn is a subset of the full JRE.

The table below lists packages that are comprised in each profile. To see how the IDE checks whether classes used in your project belong to the specified profile, select Compact1 as a profile for the AnagramGame project and click OK.

The IDE displays errors to notify that the AnagramGame project is not compliant with the compact1 profile. Lambda expressions address the bulkiness of anonymous inner classes by expressing the machinery of anonymous inner classes more compactly.

The general syntax of a lambda expression consists of a set of parameters, an arrow token, and a function body either a single expression or a statement block :.

NetBeans IDE detects pre-lambda expressions and displays the hints in the Editor proposing to turn such constructs into lambda expressions. For example, the AnagramGame project features a pre-lambda construct in the Anagrams. If the Use Lambda hint is selected, the IDE converts the anonymous inner class into a lambda expression.

If you choose the Run Inspect on option, the IDE displays the Inspect dialog box that allows to run a single Convert to Lambda inspection on the specified file.

Back to '1. Log in or Sign up to track your course progress, gain access to final exams, and get a free certificate of completion! Using an IDE means that you have all of the tools you need in one place your "development environment" instead of having to organize things manually. Use the instructions in Step 2 to write a simple Java program called "Hello. How to Install NetBeans 8.

Step 2: Run the Installer Run the downloaded installer. For beginners, choose "Java SE" e. Double-click the " NetBeans 8. Eject the Disk Image ". You shall receive a sh file e. Set the downloaded sh file to executable and run the sh file. Mark as completed. When developing your application, you can use annotations in your class to specify the persistent context instance of your entity instances.

The life-cycle of the entity instances is then handled by the container. You can keep the other default options persistence unit name, EclipseLink persistence provider. Confirm that the persistence unit is using the Java Transaction API and that the Table Generation Strategy is set to Create so that the tables based on your entity classes are created when the application is deployed.

When you click Finish, the IDE creates the entity class and opens the class in the editor. In the Generate Getters and Setters dialog box, select the message field and click Generate.

The entity class represents a table in the database. When you run this application, a database table for Message will be automatically created.

The table will contain the columns id and message. This specifies that the responsibility for managing the lifecycle of entities in the persistence context is assigned to the container.

This results in less code because the entity lifecycle is managed by the container and not by the application. In this exercise you will use a wizard to create a stateless session facade for the Message entity. The EJB 3.

In this application where the client accessing the bean is a local client, you have the option to use a local interface or a no-interface view to expose the bean.

Notice that you did not need to create a business interface for the session bean. Instead, in this application the bean will be exposed to a local managed bean using a no-interface view. As you can see in the generated code, the annotation Stateless is used to declare MessageFacade. In this example the name of the persistence unit is declared explicitly, but the name is optional if the application has only one persistence unit. You can see that the IDE generates some commonly used default query methods that can be used to find entity objects.

Starting with JSF 2. You are no longer required to add entries in the faces-config. You can use bean names in JSF pages to access methods in the managed bean. For more about the JavaServer Faces 2. In this exercise you will create a simple JSF managed bean that is used to access the session facade. When you click Finish, the IDE creates the bean class and opens the class in the editor. In the Projects window you will see the following files.

You will now add an EJB annotation to use dependency injection to obtain a reference to the MessageFacade session bean. You will also call the findAll and create methods that are exposed in the facade. Notice that the postMessage method returns the string "theend". In this application, no navigation rules are configured in faces-config. Instead, the navigation handler will try to locate a suitable page in the application. In this case, the navigation handler will try to locate a page named theend.

In this exercise you will make some simple changes to the index. You will add a form with an input text field and a button. The postMessage method will return "theend", and the navigation handler will look for a page named theend. In this exercise you will create the JSF page theend.

The page will be displayed when the user clicks the Post Message button in index. When you choose Run, the IDE builds and deploys the application and opens index.

When you click Post Message, the message is saved to the database and the number of messages is retrieved and displayed. Download a zip archive of the finished project.
