Java Programming

  • Java date format

    Date value needs to format for various programming purposes. One of the essential reasons to format the date is to represent the date value in a human-readable format. Many classes exist in Java to format the date value. DateTimeFormatter and SimpleDateFormat are two of them. These classes can be used to format date values in different ways. How these two classes can be used to format the date in Java is explained in this tutorial.

  • Java Enum Tutorial

    Java enum is a special Java type that defines by a Java class. It is also called the Java enumeration type. It is introduced in Java version 5 first, which is mainly used to define the collection of constants. The compile type of safety is ensured by using the enum type. So, when all possible values of the variable are known before compile time, then it is better to use enum type. It defines a class that always extends from java.lang.Enum. How enum type can be declared and used in Java are shown in this tutorial.

  • Java Abstract Class

    The concept of the abstraction is to highlight the task of the object instead of highlighting, “how the object does the task”. This type of concept can be implemented by using two ways in Java. These are the abstract class and interface. Abstract class contains the keyword abstract. This class can not be initiated like other normal classes, but a subclass can be derived by inheriting the abstract class. The features of the abstract class can be accessed by creating the object of the subclass. An abstract class can also contain the constructor that can be accessed by creating the object of the subclass class. How you can use an abstract class in Java is shown in this tutorial.

  • Java exception handling

    When the normal flow of the program execution interrupts for any error, then it is called an exception. This type of event can be handled by using a try-catch-finally block. An exception is an object that is used to catch the error and run the statement based on the error condition that is called exception handling. Mainly two types of error are handled by exception handling. These are compiled time errors and run-time errors. The run-time errors are handled by exception handling. How you can handle exceptions in Java is explained in this tutorial.

Tiny module and dev kit run RT Linux on STM32MP1

Exor’s 25.4 x 25.4mm, extended temp “NanoSOM nS02” module runs real-time Linux and its XPlatform industrial IoT software on a soldered, 800MHz STM32MP157 with up to 1GB DDR3L and 32GB eMMC. An “OpenHMI nS02” dev kit with 5-inch touchscreen is optional. Italian embedded technology firm Exor Embedded has launched a NanoSOM nS02 module that runs real-time Linux on the new 800MHz version of ST’s dual-core, Cortex-A7 based STM32MP157. As with the recent, Apollo Lake based, FPGA-enabled GigaSOM GS01 module, Exor announced the product with Arrow, which will be distributing the module and an OpenHMI nS02 Development Kit (see farther below).
