ClassNotFoundException

ClassNotFoundException is a checked exception, thrown when an Application tries to load the class using name, but the class doesn't exist.

public class LoadClass {
    public static void main(String args[]) throws ClassNotFoundException{
        Class.forName("NoClass");
    }
}
