How to check if a Class Exists in Java

How to check if a Class Exists in Java

1). Using Class.forName()

In this way, we are using the reflection for the class existence check.

It will throw ClassNotFoundException if the class not found.

try {
	Class yourClass = Class.forName("classname");
	Object object = yourClass.newInstance();
} catch(ClassNotFoundException e) {
	//Throw error or whatever
}

2). Check If Class Exists in the given path

We can create a file giving that path and check whether that file exists or not.

File classFile = new File("path/YourClass.class");
if (fileTest.exists()) {
	System.out.println("exists");
	//Instantiate the class.
} else {
	System.out.println("not exists");
}
