Java Packages & Import Statements Deep Dive | Java Mastery Series
Hey guys! Welcome back to Phase 3 of the Java Mastery Series. Today, we are taking a deeper look at Packages and how to properly use Import statements in our projects.
We start with a quick recap on packages to help prepare us for Java Modules later on, and discuss the industry standards for package naming conventions. Then, we break down the different ways to import code—like single type, on-demand, fully qualified names, and static imports. We also cover some hidden Java magic, like how the java.lang package is automatically imported for you, what the default package is, and what that weird package-info.java file is actually used for.
Hope this helps you organize your code better! Let me know in the comments if anything is confusing you.
