What is polymorphism in Java and how can it be applied while coding?

I have the textbook definition of it, but I don’t understand it. Can someone explain it to me in simpler terms and explain how it can be applied to coding?

Answer #1
Answer #2

Single polymorphism is achieved by method overriding. Listing 1 provides an example of single polymorphism, demonstrating how classes that implement the Traceable interface simply write their current state to System.out. Instances of Traceable can be registered with the TraceManager, which will invoke the Trace() method on each of these instances in TraceAll().
