Usage Useful when key-value mapping is required Useful when the uniqueness of elements is required Purpose Stores key-value pairs Stores unique elements (values) Types of HashMaps Mentioned below are the various types of HashMaps in Java: LinkedHashMap: LinkedHashMap extends the functionality of...
Java 8 is a giant step forward for the Java language. Writing this book has forced me to learn a lot more about it. In Project Lambda, Java gets a new closure syntax, method-references, and default methods on interfaces. It manages to add many of the features of functional languages wit...
For instance, a FlowForce job might execute a complex data mapping that calculates real-time sales report figures, then delivers the report instantly to the MobileTogether app user in a beautiful, native-client form. Now, in addition to specifying a FlowForce job as a data source, ...
Mapping Stage: This is the first step of the MapReduce and it includes the process of reading the information from the Hadoop Distributed File System (HDFS). The data could be in the form of a directory or a file. The input data file is fed into the mapper function one line at a tim...
But that’s not the only way APIs make our everyday lives easier. They enable the geolocation services used by apps that provide ride-sharing or food delivery services that depend on mapping APIs to find the location of a customer’s home or destination. ...
In 3D computer graphics, not every detail of a 3D model needs to be modeled or sculpted in the object’s geometry, thanks to normal mapping. This technique is used to create illusory surface details to enhance the realism of digital objects without increasing geometric complexity. ...
But traditional robotics did have significant impact in one area, through a process called “simultaneous localization and mapping” (SLAM). SLAM algorithms helped contribute to self-driving cars and are used in consumer products like vacuum cleaning robots and quadcopter drones. Today, this work has...
BeforeUpdate += entity => { if (entity is BaseEntity baseEntity) { baseEntity.LastUpdateOn = DateTime.Now; } }; //Add custom type mapping //x.SetParameterTypeMap(typeof(DateTime), DbType.DateTime2); //Add custom field mapping handler //x.SetTypeHandler(typeof(Guid), new GuidTypeHandler...
Gather data.Spatial mapping techniques are used to gather data around the user and the device's surroundings. Techniques such as photogrammetry,lidar and radar capture a 3D modelof the world. Lidar or radar measure the reflection of a laser or radio signal off objects around a scanner to autom...
Flowcharts for Software Engineering or Programming These charts can describe highly technical information in a clearer way. While coding or working in software, diagrams can: Show how users navigate a page or use an application Describe how code is structured or organized ...
