How to check if a folder exists in Java through a source code

Java is an all purpose programming language particularly designed to have as much less application dependencies as possible. Java implementations are usually compiled to byte code that helps to run any Java virtual machine.

Java is one of the most famous programming languages in vogue, especially for client server web execution. This program was evolved by James Gosling at Sun Microsystems. Java retains most of its syntax from C and C++. And it does not have much high level facilities.

Here is the video tutorial of "How to check if a folder exists in Java?":

In this video we will explain about a source code through which we can check if a folder exists or not in Java.

1. A new Java project is created by clicking on the file - new - project -Java project - next. It was named 'folder check'.


2. A new package is also created by clicking on the file - new - package and then the package was named.


3. Then a class is created in the similar way.


4. The source code is then copied.


5. In the eclipse folder we check out if a folder exists or not. If it is true then the file or directory exists and if it is not true then the file or directory does not exist.


6. If we run it in java application it will show that the folder exists.


7. If we change something then it will show that the folder does not exist.


8. Thus we can check out if our folder exists in Java by the help of source code in a few simple steps.
