What is the difference between compile time and runtime in java

If a program contains runtime error, it won't run successfully, rather that error will be displayed in command window eg.

Let us suppose if you wrote a program MyFirstProgram. Exception in thread "main" java. In other way, in compile time java source code. While in runtime, the java virtual machine loads the. Compile time errors are the error that comes while compiling the program whereas runtime errors are errors that comes at the time of execution run-time of the program. An example of compile time error is "not adding a semicolon ; at the end of a statement" in your java program while "dividing a number by zero" is an example of runtime error.

In this article, we will see the difference between two types of polymorphisms, compile time and run time. Compile Time Polymorphism: Whenever an object is bound with their functionality at the compile-time, this is known as the compile-time polymorphism.

At compile-time, java knows which method to call by checking the method signatures. So this is called compile-time polymorphism or static or early binding. Compile-time polymorphism is achieved through method overloading. Method Overloading says you can have more than one function with the same name in one class having a different prototype. Function overloading is one of the ways to achieve polymorphism but it depends on technology that which type of polymorphism we adopt.

In java, we achieve function overloading at compile-Time. The following is an example where compile-time polymorphism can be observed. Attention reader! Free Software Development Course.

This is when a code is run in the runtime environment and starts from the time code execution starts till the point the user or OS stops the code.
