Exception And Types of Exceptions in Java

What is checked exception and unchecked exception?

A checked exception must be handled either by re-throwing or with a try catch block, a runtime isn't required to be handled. An unchecked exception is a programming error and are fatal, whereas a checked exception is an exception condition within your codes logic and can be recovered or retried from.

What is difference between runtime exceptions and plain exceptions?

Main difference between RuntimeException and checked Exception is that It is mandatory to provide try-catch or try finally block to handle checked Exception and failure to do so will result in a compile-time error, while in the case of RuntimeException this is not mandatory.

How many types of exceptions are there in selenium?

Selenium exceptions are divided into two types including Checked Exceptions and Unchecked Exceptions. Checked Exceptions are handled during the process of writing codes.

What are the exceptions in Java?

Java Exception Handling is a mechanism to handle runtime errors such as ClassNotFoundException, IOException, SQLException, RemoteException, etc. Exception is an unwanted or unexpected event, which occurs during the execution of a program, i.e. at run time, that disrupts the normal flow of the program's instructions.

What is runtime exception and compile-time exceptions?

Runtime. The compile-time errors are the errors which are produced at the compile-time, and they are detected by the compiler. The runtime errors are the errors which are not generated by the compiler and produce an unpredictable result at the execution time.

What are runtime exceptions?

RuntimeException is the superclass of those exceptions that can be thrown during the normal operation of the Java Virtual Machine. RuntimeException and its subclasses are unchecked exceptions.

Is arithmetic exception a runtime exception?

ArithmeticException inherits from the RuntimeException class which means it is an unchecked, runtime exception [2].

What's a checked exception?

A checked exception is a type of exception that must be either caught or declared in the method in which it is thrown. For example, the java.io.IOException is a checked exception.

Which is an example of unchecked exception?

Some common unchecked exceptions in Java are NullPointerException, ArrayIndexOutOfBoundsException and IllegalArgumentException.

What are unchecked exceptions in Java?

An unchecked exception is the one which occurs at the time of execution. These are also called as Runtime Exceptions. These include programming bugs, such as logic errors or improper use of an API. Runtime exceptions are ignored at the time of compilation.

What is compile-time exception?

A checked exception is an exception that occurs at the compile time, these are also called as compile time exceptions. These exceptions cannot simply be ignored at the time of compilation, the programmer should take care of (handle) these exceptions.

What is arithmetic exception in Java?

java.lang.ArithmeticException. Thrown when an exceptional arithmetic condition has occurred. For example, an integer "divide by zero" throws an instance of this class. ArithmeticException objects may be constructed by the virtual machine as if stack trace was not writable.

What is difference between compile and runtime?

Compile time is the period when the programming code (such as C#, Java, C, Python) is converted to the machine code (i.e. binary code). Runtime is the period of time when a program is running and generally occurs after compile time.

What are the two exception classes in hierarchy of Java exception class?

The Exception class has two main subclasses: IOException class and RuntimeException Class.

What is exception and error in Java?

Errors mostly occur at runtime that's they belong to an unchecked type. Exceptions are the problems which can occur at runtime and compile time. It mainly occurs in the code written by the developers. Exceptions are divided into two categories such as checked exceptions and unchecked exceptions.
