Intent

Provide a template to suppress any exceptions that either are declared but cannot occur or should only be logged; while executing some business logic. The template removes the need to write repeated try-catch blocks.

Applicability

Use this idiom when

• an API declares some exception but can never throw that exception eg. ByteArrayOutputStream bulk write method.
• you need to suppress some exception just by logging it, such as closing a resource.
