User-defined Custom Exception in Java
Java provides us facility to create our own exceptions which are basically derived classes of Exception. For example MyException in below code extends the Exception class.
We pass the string to the constructor of the super class- Exception which is obtained using “getMessage()” function on the object created.
In the above code, constructor of MyException requires a string as its argument. The string is passed to parent class Exception’s constructor using super(). The constructor of Exception class can also be called without a parameter and call to super is not mandatory.
