What are some common Java exceptions and how can I handle them?

What are some common Java exceptions I should know about?

Some common Java exceptions include NullPointerException, ArrayIndexOutOfBoundsException, and ClassCastException.

How can I handle a NullPointerException?

You can handle a NullPointerException by checking for null values before accessing an object's methods or properties.

What about ArrayIndexOutOfBoundsException?

To handle ArrayIndexOutOfBoundsException, ensure that your index is within the bounds of the array before accessing it.

Can you give me an example of handling exceptions in a try-catch block?

Sure! Here's an example:

try {
    int[] arr = new int[5];
    System.out.println(arr[10]); // This will throw an exception
} catch (ArrayIndexOutOfBoundsException e) {
    System.out.println("Index is out of bounds!");
}
