Compile Time Polymorphism in Java is when you have the several methods with same name and different parameters and compiler has to decide how to select which method has to run based on the arguments hence the name Compile time polymorphism or method overloading.

What is Difference between dynamic polymorphism and static polymorphism with example?
Static polymorphism is used the concept of early binding or we can say compile time binding where as dynamic polymorphism used the concept of late binding or run time binding.
What is dynamic method dispatch in java?
dynamic method dispatch is a technique by which a call to a overridden method is solved at runtime rather than compile time..this is how java implements runtime polymorphism.
Why run time polymorphism is dynamic and compile time polymorphism is static?
The simple answer is that compile-time polymorphism occurs at compile time while runtime polymorphism occurs at runtime. The actual answer is that compile-time polymorphism results in the compiler generating source code on your behalf while runtime polymorphism relies on function pointers or virtual methods to determine the next instruction at runtime. Compile-time polymorphism therefore applies to template functions and classes since that is the only way the compiler can generate source code on your behalf. To achieve this, the runtime type for the template parameters must be fully-defined at compile time, even if those types have runtime polymorphic characteristics of their own. Runtime polymorphism applies to virtual methods and function pointers, both of which can be used to dynamically alter the execution path of your program. Virtual methods are made possible through virtual tables, which are essentially just arrays of function pointers. Each runtime type that derives from a base class with virtual methods provides its own virtual table, thus the runtime type determines which specific function overrides will be invoked at runtime, even if the runtime type cannot be determined at compile time. In this way you can generalise your code to work with the base type but still get the expected polymorphic behaviour whenever a derived type is passed instead.
What is the command to compile a java program named Greetingsjava?
The command to compile a Java program is "javac", followed by the class name (file name).
How do you compile and execute Java program in which we find the highest of any five numbers?
In the same way as you would compile and execute any other Java program. Compile: use the "javac" command. Or use the built-in "compile" command in your favorite IDE. Execute: Use the "java" command. Or use the built-in "run" command in your favorite IDE.
Define compile time polymorphism with short examples?
compiler can decide which form of the object should be invoked during compile time.this type of polymorphism is know as compile time polymorphism
What is the difference between compile time and run time polymorphism?
Runtime prolymorphism means overriding compiletile polymorphism means overloading
Is late binding and dynamic binding related to polymorphism?
Late binding and dynamic binding are related to runtime polymorphism. By contrast, compile time polymorphism is known as static binding. Template functions and classes are examples of static binding because the exact type can be determined at compile time.

What is polymorphism and its types?
Polymorphism means multiple form of a function, variable or object. In Computer Science, polymorphism is a programming language feature that allows values of different data types to be handles using a common interface. There are three types : Ad-Hoc Polymosphism, Parametric Polymorphism, Subtype/Inclusion Polymorphism. Source: Wikipedia.
Does java supports polymorphism?
Yes.

Is Interfaces in Java a kind of polymorphism?
No. Interfaces in Java are a construct to get polymorphism ( subtype polymorphism ) working in Java, but they are not a "kind" of polymorphism. In polymorphism happens when two objects respond to the same message ( method call ) in different way ( hence poly -> many, morphism -> way or shape : polymorphism -> many ways). In Java to be able to send the same message to two different objects you have to either inherit the same parent, or implement the same interface.
How do you run and compile a java applet program?
One can run and compile a Java applet program by agreeing to the terms and downloading it. It is possible to get a compiler online that will compile and run Java programs.
How do you make software from a simple java program?
You compile it.You compile it.You compile it.You compile it.
