Java functions - The Java virtual machine (JVM) is a virtual machine that enables a computer to run Java programs. The JVM has two primary functions, which are: To allow Java programs to run on any device or operating system (this is also known as the "Write once, run anywhere" principle). And, to manage and optimize program memory.

 
2. Prefer Standard Functional Interfaces.
