Assume the below are java.lang unless I specify otherwise:
- Casting: ClassCastException
- Arrays: ArrayIndexOutOfBoundsException, NullPointerException
- Collections: NullPointerException, ClassCastException (if you're not using autoboxing and you screw it up)
- IO: java.io.IOException, java.io.FileNotFoundException, java.io.EOFException
- Serialization: java.io.ObjectStreamException (AND ITS SUBCLASSES, which I'm too lazy to enumerate)
- Threads: InterruptedException, SecurityException, IllegalThreadStateException
- Potentially common to all situations: NullPointerException, IllegalArgumentException

August 12, 2023 - In Java, exceptions are organized in a hierarchical structure that revolves around the `Throwable` class. This structure is designed to provide a systematic way of categorizing and handling different types of exceptions. The main components of the exception hierarchy are ... Checked exceptions, also known as compile-time exceptions, are exceptions that must be either caught or declared in the method signature using the throws keyword.

Java Checked vs Unchecked Exceptions - GeeksforGeeks
October 2, 2025 - Unchecked exceptions include all subclasses of the RuntimeException class, as well as the Error class and its subclasses. The separation into checked and unchecked exceptions sounded like a good idea at the time. Over the years, it has introduced more boilerplate and less aesthetically pleasing code patterns than it solved real problems. The typical pattern within the Java ecosystem is to hide the checked exception within an unchecked one.

11.2. Compile-Time Checking of Exceptions
September 16, 2025 - For example, certain code might implement a circular data structure that, by construction, can never involve null references; the programmer can then be certain that a NullPointerException cannot occur, but it would be difficult for a Java compiler to prove it. The theorem-proving technology that is needed to establish such global properties of data structures is beyond the scope of this specification. We say that a statement or expression can throw a checked exception class E if, according to the rules in §11.2.1 and §11.2.2, the execution of the statement or expression can result in an exception of class E being thrown.

r/java on Reddit: If everyone hates checked exceptions, where's the alternative?
April 25, 2024 -
Many a blog post has been written about how Checked Exception are bad/the devil incarnate.
For all the bloviating about how bad it is, most of these articles and their comment sections lack any concrete alternatives.
For Java versions before 21, there simply doesn't seem to be a reasonable (never mind close to standardized) alternative to express that a method returns Thing or AException or BException.
For Java 21+, with sealed classes and exhaustive switches, you kind of can manually recreate a vague resemblance of e.g. Rusts Result Type. That will still lack some necessities, like enforcing checking the Error for Void methods (as in Result<Void, Err>).
So my question is:
If you agree that checked exceptions are bad, what alternative are you actively using right now?
How is your favorite library handling this? Because most still seem to use exceptions
Personally, I'm getting reaaaallly annoyed by the way people talk about exceptions online. For one, they'll point out a problem, but then fail to demonstrate a solution that wouldn't have it. For another, there's very little will, it seems, to suggest and work towards a serious alternative. How can we, as a community, warn against using a builtin feature for an important part of programming without providing alternatives? Aren't we simply screwing over newbies with these takes?

Checked exceptions are the right tool for the job they're designed for, they simply get misused. An unexpected error but there are ways to recover -> checked exception. Example : Server unavailable. Recovery possibility: retry the operation at a later time. If there is not a way to recover it should not be a checked exception. It should be an unchecked exception. Example -> NullPointer. Something is not right somewhere, and retrying isn't going to fix it. If it is not an unexpected error (example, user enters their born on date in the future) then it should not be an exception. This should be a validation that returns some validation result, maybe just true or false, maybe a validationResult class of some sort.

What you're observing is that for any endeavor, the haters often dominate the discourse, even when they don't have a majority position or a credible alternative. If they didn't hate on exceptions, they'd be whining about something else. Error handling is hard; there are many different approaches (C-style single return codes, Go-style multiple return codes, unchecked exceptions, checked exceptions, try monads, and more), and each has their pros and cons (and their supporters and haters), striking different balances of reliability and intrusiveness. Thinking there is One True Best Way here is fantasy. When people react to a particular error model, they are often reacting not to the approach itself, but examples they've encountered where it is used poorly. (Certainly Java has no shortage of examples of checked exceptions being misused.) The reality is that checked exceptions are OK, and they're what we've got, and, even if there was something that was slightly better, the disruption of trying to migrate billions of lines of code would make that impractical -- it would have to be massively better, and there's no such candidate on the horizon. Most developers intuitively realize this, and are not interested in dying on this hill, so you don't hear them in the vocal discourse, because they're too busy getting their work done. So if you want to know what to tell the newbies, tell them: don't take every rant seriously, some people just like to rant.

NoClassDefFoundError extends LinkageError Thrown if the Java Virtual Machine or a ClassLoader instance tries to load in the definition of a class (as part of a normal method call or as part of creating a new instance using the new expression) and no definition of the class could be found. The searched-for class definition existed when the currently executing class was compiled, but the definition can no longer be found. Checked Exceptions IOException extends Exception Signals that an I/O exception of some sort has occurred.

This code won't compile because it can throw a checked exception. The compilation error can be resolved in either of two ways: By catching the exception and handling it, or by declaring that the exception can be thrown using the throws keyword. In the Java class hierarchy, an exception is a checked exception if it inherits from java.lang.Throwable, but not from java.lang.RuntimeException or java.lang.Error.

These exceptions are checked at compile-time. Unchecked Exceptions: The unchecked exceptions are not handled by the programmer. These exceptions are thrown on run-time. Some of the unchecked exceptions are NullPointerException, ArrayIndexOutOfBoundsException, ArithmeticException, etc. Java defines several other types of exceptions that relate to its various class libraries. Following is the list of Java Unchecked and Checked RuntimeException.

If a client cannot do anything to recover from the exception, make it an unchecked exception.
