Implementing Inheritance in Java

Summary

The video explains inheritance in Java, part of object-oriented programming. Alex sets up a Java project and uses a gaming mouse example to illustrate concepts. He creates classes like Mouse1, Mouse2, and Mouse3, each with properties such as texture and methods like leftClick and rightClick. Mouse1 includes an additional RGB feature. This demonstrates how objects can be defined to prepare for inheritance, helping to structure code efficiently without repetition.
