Groovy vs. Java syntax discrepancy
groovy, java, syntax
Solution
The problem is that Groovy doesn't require explicit line terminators - and `return a` looks like a valid statement on its own. You could use:
return a &&
b &&
c;
Or use a line continuation:
return a \
&& b \
&& c;
It's not true that all Java is valid Groovy. While most Java syntax is covered, occasionally a feature of Groovy will have an impact on valid Java.
Problem
In Java I can do this: ``` return a && b && c; ``` In Groovy, it returns a compile error: `unexpected token: &&`. It also occurs if I omit the `return` keyword in Groovy. However if I wrap the statement in parentheses, it works fine. In all the Groovy resources I've read, I've been told that I should be able to write "straight Java" wherever I want. Is this a bug? If not, what is the reason for this design decision? I looked here, but did not find this issue listed. I understand that there are some things that cannot be inherited from Java, but this wouldn't seem like one of those things.
