How is error handling implemented in Java?

In Java, the error handling mechanism is implemented using exceptions. Exceptions allow separating the normal execution flow from error handling.

Main keywords:

• try — a block where an exception may occur.
• catch — a block that catches and handles the exception.
• finally — a block that always executes, regardless of whether an exception occurred or not.
• throw — an operator for generating an exception.

Example:

try {
    int result = 10 / 0; // will throw ArithmeticException
} catch (ArithmeticException e) {
    System.out.println("Division by zero is not possible");
} finally {
    System.out.println("Finally block executed");
}
