Java 8 Lambda function that throws exception?

Question

I know how to create a reference to a method that has a String parameter and returns an int, it\'s:

Function         


        

Answer 1

I will do something generic:

public interface Lambda {

    @FunctionalInterface
    public interface CheckedFunction {

        T get() throws Exception;
    }

    public static  T handle(CheckedFunction supplier) {
        try {
            return supplier.get();
        } catch (Exception exception) {
            throw new RuntimeException(exception);

        }
    }
}

usage:

 Lambda.handle(() -> method());
