Inhalt: Kotlin is an exciting programming language that's concise, has immutable variables, and almost always gets rid of null pointer exceptions. If you're a Java developer looking to get started with Kotlin, then this course is for you. Join instructor Matt Greencroft as he demonstrates how to build high-quality Spring Boot applications with Kotlin, specifically the version of Kotlin that runs on the Java Virtual Machine (JVM). As Matt covers a range of key concepts-from classes to loops-he explains how each Kotlin feature compares to the equivalent one in Java. Umfang: 07:46:46.00
Inhalt: By taking the time to learn how memory works in Java, you can avoid introducing problems in your code, as well as more effectively find and fix any memory errors that still occur. In this hands-on course, join instructor Matt Greencroft as he details how memory works in Java. Matt goes over essential concepts such as the roles of the stack and the heap, escaping references, garbage collection, detecting soft leaks, and more. Plus, he lends a real-world context to these concepts by demonstrating how to hunt for-and fix-a memory leak in a sample Java web application. While Matt works with Eclipse and Java 8 throughout the course, the material he covers is valid for any IDE and Java 6 and above. Umfang: 03:00:38.00
Inhalt: Learn how to use tests to drive the writing of your code, a key component of agile programming. More than just theory, this course covers a range of practical topics that can help Java developers get up and running with test-driven development (TDD). Instructor Matt Greencroft helps to acquaint you with the process that's required for TDD, as well as how to deal with real-world challenges you may encounter when carrying out TDD. Discover how to write your first test and determine what makes a good or bad test. Plus, learn how to test code where there's a dependency on third-party resources, how to create mocks and stubs with Mockito-a popular third-party library-and more. Umfang: 03:50:53.00
