There are two types of exceptions: checked exception and unchecked exception. In this guide, we will discuss them. The maindifference between checked and unchecked exceptionis that the checked exceptions are ch
Java compiler forces us to handle these exceptions in some manner in the application code. We must handle these exceptions at a suitable level inside the application to inform the user about the failure and ask him to retry or come later. Generally, checked exceptions denoteerror scenarios outsi...
An exception. No problem, you caught it. But wait, there's another. And another. Suddenly, you're juggling exceptions like you’re in the circus. Don't worry, Java's got your back. Java offers three ways to catch multiple exceptions: using multiple catch blocks for different exception ty...
To catch an exception in Java, you write a try block with one or more catch clauses. Each catch clause specifies one exception type that it is prepared to handle. The try block places a fence around a bit of code that is under the watchful eye of the associated catchers. If the bit ...
Learn to fix the error ‘Java 8 date/time type not supported by default’ while serializing and deserializing Java 8 Date time classes using Jackson. Resolving IllegalMonitorStateException In Java Learn IllegalMonitorStateException, when it is thrown with examples. We will also see how we can pr...
It’s always nice to borrow and steal concepts and ideas from other languages. Scala’sOptionis one idea I really like, so I wrote an implementation in Java. It wraps an object which may or may not be null, and provides some methods to work with in a more kinda-sorta functional way....
The lowercase charactereis a reference to the thrown (and caught)NumberFormatExceptionobject. This reference could have been used inside thecatchclause, although in this case it isn't. (Examples ofcatchclauses that use the reference are shown later in this article.) ...

Actual cause: java.io.IOException: IO cause. 5. Why Chained Exceptions? We need to chain the exceptions to make logs readable. Let’s write two examples. First without chaining the exceptions and second, with chained exceptions. Later, we will compare how logs behave in both of the cases....
