Java 14 new features | Pattern matching for instance of operator in JDK 14

Use pattern matching for instanceof operator to simplify the use of the instanceof operator in Java, thereby making your code safer and more easier to write.

Many Java developers use the instanceof operator to compare a reference variable to a type. If the result is true, the next obvious step is to explicitly type cast it to the type they compared it with, to access its members. These steps have a repetition: compareTo.
This step is redundent. this step can be avoided when you start using the pattern matching for instnce of operator in java 14
