Run-Time Polymorphism: Runtime polymorphism occurs when an object is associated with functionality during runtime. Method overriding can be used to provide runtime polymorphism. The Java virtual machine selects the method to invoke during runtime, not at compile time. It’s also known as dyna...
4. Compile vs. Runtime Constants A variable is acompile-timeconstant if its value is computed at compile-time. On the other hand, a runtime constant value will be computed during execution. 4.1. Compile-Time Constants A Java variable is a compile-time constant if it’sof a primitive type...

The types of errors encountered when a software developer develops a Java application can be split into two broad categories: compile time errors and runtime errors. As the name implies, compile time errors occur when the code is built, but the program fails to compile. In contrast,Java run...
