How to avoid mandatory handling of IOException exception?

In Java, IOException is a checked exception that requires mandatory handling either through a try-catch block or by declaring it in the method signature with throws. To avoid mandatory handling of IOException, you can:

• Wrap the IOException in an unchecked exception, such as RuntimeException. Then, the method does not need to declare throws, and the calling code is not required to handle the exception.

Example:

public void readFile() {
    try {
        // code that might throw IOException
    } catch (IOException e) {
        throw new RuntimeException(e);
    }
}

• Use third-party libraries or utilities that handle IOException internally and provide APIs without checked exceptions.

• In Java 8+, you can use lambdas and wrappers that hide checked exceptions.

However, it is important to remember that ignoring the handling of IOException can lead to loss of input/output error information, so this approach should be used consciously.
