Description

uncheck is a very simple Java library aiming to ease the transformation of checked exceptions into runtime exceptions using lambda.

Without uncheck

Wrapping a checked exception inside a runtime exception usually requires some boilerplate code:

try {
    unsafeMethod();
} catch(Exception e) {
    throw new RuntimeException(e);
}

This can even be more verbose when the unsafe call returns a value to process:

Object result;
try {
    result = unsafeMethod();
} catch(Exception e) {
    throw new RuntimeException(e);
}

process(result);

With uncheck

Using uncheck, you can improve the readability of your code by removing the boilerplate part of it:

uncheck(this::unsafeMethod);

It also nicely handles methods returning values:

Object result = uncheck(this::unsafeMethod);
process(result);

Note

Caught exceptions are processed this way:

• RuntimeException are just propagated as they are
• IOException are wrapped inside UncheckedIOException
• other exceptions are wrapped inside RuntimeException
