java exception handling

In Java, exception handling is a mechanism to handle runtime errors that occur during the execution of a program. Exception handling allows you to detect and handle exceptions that may occur in your code, rather than having the Java runtime terminate the program.

To handle exceptions in Java, you can use the try...catch statement or the try...catch...finally statement.

The try...catch statement allows you to specify a block of code that may throw an exception, and a separate block of code to handle the exception if it is thrown. The syntax for the try...catch statement is as follows:

try {
    // code that may throw an exception
} catch (ExceptionType ex) {
    // code to handle the exception
}

The try...catch...finally statement allows you to specify a block of code that may throw an exception, a separate block of code to handle the exception if it is thrown, and a separate block of code to be executed regardless of whether an exception is thrown. The syntax for the try...catch...finally statement is as follows:

try {
    // code that may throw an exception
} catch (ExceptionType ex) {
    // code to handle the exception
} finally {
    // code to be executed regardless of whether an exception is thrown
}

You can also use the throws keyword in a method declaration to specify that the method may throw an exception. This allows the caller of the method to handle the exception or pass it on to another method.
