What type of exception does OutOfMemoryException represent in the programming language?

In Java, OutOfMemoryError (the correct name is OutOfMemoryError) is an error, not an exception. It inherits from the class java.lang.VirtualMachineError.

This means that OutOfMemoryError is a runtime error indicating that the JVM could not allocate the necessary memory. Such errors are usually not handled in code, as they point to serious resource issues.

Example:

try {
    // code that might cause OutOfMemoryError
} catch (OutOfMemoryError e) {
    System.err.println("Memory exhausted!");
    // it's usually better to terminate the program or free resources
}

But in most cases, catching OutOfMemoryError is not recommended; instead, optimize memory usage or increase its limit.
