[Shivangi Panwar]

The exception is used for exceptional condition that user's program should catch.

[pxljobs]

Exception is the problem arise during the execution of the program exception occur normal flow of the program it disrupted program terminates abnormally so it will harmful to the program so must we can handle this exception.

[medishanaik]

What pxljobs say is right. and Exception in java is a event.

[Thoughtgrid]

Generally exceptions are event occurs during execution of the program in java exception is an object wrap an error event occur within a method the main uses of exception are separate error handling code from regular code,standardize error handling.

Exceptions are events that occur during the execution of programs that disrupt the normal flow of instructions (e.g. divide by zero, array access out of bound, etc.). In Java, an exception is an object that wraps an error event that occurred within a method and contains: Information about the error including its type.

Exceptions are the customary way in Java to indicate to a calling method that an abnormal condition has occurred.

The exception handling in java is one of the powerful mechanism to handle the runtime errors so that normal flow of the application can be maintained. In this page, we will learn about java exception, its type and the difference between checked and unchecked exceptions.

[jackar56]

The built-in exceptions in Java are categorized on the basis of whether the exception is handled by the Java compiler or not. Java consists of the following categories of built-in exceptions:

- Checked Exceptions
- Unchecked Exceptions

In general, unchecked exceptions represent defects in the program (bugs), which are normally Runtime exceptions.
Furthermore, checked exceptions represent invalid conditions in areas outside the immediate control of the program.

1)Checked Exception:

In general, unchecked exceptions represent defects in the program (bugs), which are normally Runtime exceptions.

The classes that extend Throwable class except RuntimeException and Error are known as checked exceptions e.g.IOException,SQLException etc. Checked exceptions are checked at compile-time.

2)Unchecked Exception:

The classes that extend RuntimeException are known as unchecked exceptions e.g. ArithmeticException,NullPointerException etc. Unchecked exceptions are not checked at compile-time.
