JVM and programmatic exceptions

Question

Aryan Kumar · Answer

JVM and programmatic exceptions are two different types of exceptions in Java.
JVM exceptions are thrown by the Java Virtual Machine (JVM). These exceptions are typically caused by programming errors, such as trying to divide by zero or accessing a null reference. JVM exceptions are unchecked, which means that they are not checked at compile time.Programmatic exceptions are thrown by the programmer. These exceptions are typically used to indicate errors that can be programmatically recovered from, such as an invalid input value. Programmatic exceptions are checked, which means that they are checked at compile time.
Here is a table that summarizes the differences between JVM and programmatic exceptions in Java:
Feature
JVM Exceptions
Programmatic Exceptions
Caused by
JVM
Programmer
Checked
No
Yes
Handled at compile time
No
Yes
Examples
NullPointerException, ArrayIndexOutOfBoundsException, ArithmeticException
IllegalArgumentException, IllegalStateException, IOException
Here are some additional details about JVM and programmatic exceptions:
JVM exceptions are typically caused by programming errors. These errors are not usually recoverable, so it would be burdensome to require programmers to handle them.Programmatic exceptions are typically used to indicate errors that can be programmatically recovered from. For example, a method that validates user input might throw a
IllegalArgumentException if the user enters an invalid value.JVM exceptions are unchecked, which means that they are not checked at compile time. This means that a method does not have to handle or specify a JVM exception. If a JVM exception is thrown, the program will simply crash.Programmatic exceptions are checked, which means that they are checked at compile time. This means that a method must handle or specify a programmatic exception. If a programmatic exception is thrown and is not handled or specified, the compiler will not allow the code to compile.
