Well, I wouldn't go as far as actually using wrapFunction, but for example it could look like this:

(excuse the formatting, I don't think medium supports code blocks in comments)

return wrappedFunction()

.flatMap(this::foo)

.flatMap(this::bar);

// usually Result types also offer more functions that can be implemented using the give ones

// e.g. .orElse(DEFAULT_VALUE);

Instead of doing

String wrappedStr;

try {

wrappedStr = wrappedFunction()

} catch (Exception ex) {

return null; // if I want to catch it

}

return foo(bar(wrappedStr));

The standard java APIs even sometimes have a monad as result. For example the stream API sometimes returns an Optional:

list.stream()

.filter(this::someFilter)

.findFirst() // this returns an Optional – essentially a result without the exception

.default("default");
