Using Try-With-Resources to Prevent Memory Leaks in Java
Contrary to popular belief, you can have memory leaks in Java. Often, they are the result of objects that use system resources not being closed properly. Java gives us a few strategies for making sure that those kinds of objects always get closed.
In this video I'll walk you through:
How these types of memory leaks occur
Using Try/Catch/Finally to fix the problem

ABOUT MY CHANNEL
My channel is about good software engineering practices. We cover introductions to programming in C and Java. But I also have lots of software and computer engineering topics like PIC programming, advanced programming techniques, and things that distinguish good code from code that works.
