However in some cases they would be inappropriate and annoying. In this course, we will cover additional language features that enable the class library, essential library areas, and provide roadmaps to areas for self-exploration. The SuppressWarnings annotation type allows Java programmers to disable compilation warnings for a certain part of a program (type, field, method, parameter, constructor, and local variable).
There are over 4200 classes in the Java 8 class library, with 100s of new ones compared to prior versions of Java. The Core Java Specialization is part of a series of programming specializations, derived from LearnQuest's private Java Bootcamps, designed to provide the skill set necessary to be hired as an IT developer using Java in many corporate environments.Īfter completing this course, you will be able to write reusable code that remains type-safe using Java Generics, work with collections of objects, work with files, handle runtime errors, and generally be prepared to move on to learning to use Java frameworks such as Spring Boot and Jakarta EE.
Note: Make sure you use the -target:jvm-1.8. Java Class Library is the fourth and final course in the Core Java Specialization. When writing Scala code which interoperates with Java, there are a few differences in annotation syntax to note.
