Core Java Training - Class 32 - Java Packages & API - package in java packages and API *Java Packages & API* A package in Java is used to group related classes. Think of it as a folder in a file directory. We use packages to avoid name conflicts, and to write a better maintainable code. Packages are divided into two categories: Built-in Packages (packages from the Java API) User-defined Packages (create your own packages) Built-in Packages The Java API is a library of prewritten classes, that are free to use, included in the Java Development Environment. The library contains components for managing input, database programming, and much much more. The complete list can be found at Oracles website: https://docs.oracle.com/javase/8/docs/api/. The library is divided into packages and classes. Meaning you can either import a single class (along with its methods and attributes), or a whole package that contain all the classes that belong to the specified package. To use a class or a package from the library, you need to use the import keyword: Syntax import package.name.Class; // Import a single class import package.name.*; // Import the whole package User-defined Packages To create your own package, you need to understand that Java uses a file system directory to store them. Just like folders on your computer: Example └── root └── mypack └── MyPackageClass.java Please Subscribe to Update on Up Coming Videos https://www.youtube.com/channel/UCOHEs9-RCCNw3DWORGM7ybw?sub_confirmation=1 Connect with me on Facebook: https://www.facebook.com/kingdeveloper1 #KingDeveloper #javapackages #packageinjava #java #tutorialjavatutorialforbeginners java packages ,java packages tutorial, java packages explained, java, package in java, package, what is java packages, packages in java, java tutorial, what is package in java, java for beginners, java course online, edureka, packages, java programming, core java, java tutorial for beginners, learn java, programming, classes, example, how to program, class 32, core java training, king developer, java util package tutorial yt:cc=on, java api, java api tutorial, what is java api, java api download, rest api java, java rest api, java collection api, java transaction api, java api programming, java api for restful web services, java api development, java api tutorial for beginners, java api testing, java web services, rest web services, soap web services, resful api, developing restful api, java programming, java training, java certification, java edureka, edureka, java tutorial java, java programming ,api, java api,java packages,java class,method,user-defined,import statement package in java,java util package tutorial,java util concurrent,packages in java,java programming,java packages,java package program,java introduction,java training,java basics,java for beginners,java tutorial,java,edureka,how to create package in java,package java,java tutorial hindi,package creation,core java training,king developer,Java Packages & API -~-~~-~~~-~~-~- Please watch: "King Developer" https://www.youtube.com/watch?v=MvoXC13_hKc Subscribe my Channel : https://www.youtube.com/@KingDeveloper?sub_confirmation=1 -~-~~-~~~-~~-~-
