The Difference Between Checked and Unchecked Exceptions in Java

In Java, exceptions are categorized into two main types: checked exceptions and unchecked exceptions.

Checked Exceptions

Checked exceptions are the exceptions that are checked at compile time. This means that the code must handle or declare these exceptions using a try-catch block or by specifying them in the method signature using the throws keyword.

Example of a checked exception in Java is IOException:

try {
    FileInputStream file = new FileInputStream("example.txt");
} catch (IOException e) {
    System.out.println("An error occurred while reading the file.");
}

Unchecked Exceptions

Unchecked exceptions, also known as runtime exceptions, do not need to be declared in the method signature or handled explicitly. These exceptions occur at runtime and are not checked by the compiler.

Example of an unchecked exception in Java is NullPointerException:

String str = null;
System.out.println(str.length()); // This will throw a NullPointerException

In summary, checked exceptions must be declared or handled, while unchecked exceptions do not require explicit handling in Java.
