Complete Java SE 8 Developer Bootcamp - Editions and Versions

The video tutorial discusses the complexity of choosing the right Java platform, focusing on the Java Virtual Machine (JVM) and its compatibility with different hardware and operating systems. It explains the three primary editions of Java: Java SE (Standard Edition), Java EE (Enterprise Edition), and Java ME (Micro Edition), along with Java FX for graphical user interfaces. The tutorial also covers the evolution of Java versions, highlighting the importance of version numbering and backwards compatibility, and how these affect the use of libraries and features in Java applications.

What is the primary role of the Java Virtual Machine (JVM)?

• To manage memory allocation for Java programs

• To compile Java code into bytecode

• To interpret bytecode into machine code for specific hardware

• To provide a graphical user interface for Java applications

How did the version numbering change after Java 1.4?

• It was replaced by year-based numbering

• It continued with decimal points like 1.5, 1.6

• It started using letters like A, B, C

• It switched to whole numbers like 5, 6, 7

What does backwards compatibility in Java versions mean?

• Java code is compatible with all operating systems

• Newer code can run on older platforms

• Older code can run on newer platforms

• Java code can be compiled with any version

If a library is compiled with Java SE7, on which platform can it run?
