public static IntBinaryOperator intBinaryOperator(CheckedIntBinaryOperator operator) {
        return Unchecked.intBinaryOperator(operator, Unchecked.RETHROW_ALL);

Wrap a {@link CheckedIntBinaryOperator} in a {@link IntBinaryOperator}.
<p>
Example:
<pre><code>
IntStream.of(1, 2, 3).reduce(Unchecked.intBinaryOperator((i1, i2) -> {
    if (i2 &lt; 0)
        throw new Exception("Only positive numbers allowed");

    return i1 + i2;
}));
</code></pre>
