Exception handling in Java is extremely important because it helps maintain the normal, desired flow of the program even when unexpected events occur. If exceptions are not handled, programs may crash or requests may fail.

In this course, you will analyze the syntax of exception handling, case by case, to understand what could happen in each variation. You’ll start by looking into multiple cases using the try-catch block, things like what happens if you throw multiple exceptions.

You’ll then look at exception handling and use cases around the syntax of the usage of finally, another popular exception block.

Lastly, you’ll experiment with the throw block and creating your own custom exceptions. By the end of this course, you will have a good grip on exception handling and its various syntaxes and use cases.

Java Exception Handling Made Simple

# Declaring throws
The throw keyword is mainly used in a method’s body. We can use the throw keyword multiple times.

However, we can also declare exceptions in the method's signature using another keyword, i.e, `throws`.

class Exceptions {
    public static void main( String args[] ) {
      readFile("filename.text");
    }

    public static void readFile(String path) throws RuntimeException{ //UncheckedException
      //code here
      System.out.println("Reading File");
    }
}

Here, the `readFile` method uses `throws` to declare an exception. It’s then the caller method's job to handle the exception.

However, **it is an unchecked exception, so it's not required to be handled**. In the case of a checked exception, it must be handled.

In this lesson, we'll walk through the syntax and usage of the throws keyword.
