Hierarchy of Exception in Java

The basic exception root class of Java is java.lang.Throwable class. We explain some common exceptions and errors. These are divided into two main classes: exception and error.

IOException:-

It belongs to the input and output operation. It works when reading, writing, and searching files. It is also called a checked exception.

NumberFormatException:-

It represents an attempt to convert a string into a numeric value such as a float or integer.

AirthmeticException:-

It represents an invalid arithmetic exception, such as a division by zero.

This error occurs when the allocated memory overflows the stack.
