In Java, exceptions are events that disrupt the normal flow of a program. They are categorized into two main types: Checked exceptions are exceptions that are checked at compile-time.
The compiler requires the programmer to handle these exceptions explicitly, either by using a try-catch block or declaring them with the throws keyword.
Unchecked exceptions are not checked at compile-time, meaning the compiler doesn't force you to handle them. They occur at runtime, often due to programming errors like logic mistakes.
