[ https://issues.apache.org/jira/browse/GROOVY-8586?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16475330#comment-16475330 ]
Daniel Sun commented on GROOVY-8586:
------------------------------------
Examples:
[https://dzone.com/articles/try-with-resources-enhancement-in-java-9]
{code:java}
public void loadDataFromDB() throws SQLException {
Connection dbCon = DriverManager.getConnection("url", "user", "password");
try (dbCon; ResultSet rs = dbCon.createStatement().executeQuery("select * from emp")) {
while (rs.next()) {
System.out.println("In loadDataFromDB() =====>>>>>>>>>>>> " + rs.getString(1));
}
} catch (SQLException e) {
System.out.println("Exception occurs while reading the data from DB ->" + e.getMessage());
}
}
{code}

> Key: GROOVY-8586
> URL: https://issues.apache.org/jira/browse/GROOVY-8586
> Project: Groovy
> Issue Type: Improvement
> Components: Compiler
> Affects Versions: 3.x
> Reporter: Jesper Steen Møller
> Assignee: Daniel Sun
> Priority: Minor
>
> Java 9 introduces a ARM-with-existing-resources construct, like this:
> {code:java}
> OutputStream stream = foo();
> try (stream) {
> stream.write(whatever());
> }
> {code}
> In other words, the resource need not be in the form of an initialization, but can just be a variable.
> Now that we have ARM in Groovy, we should be able to add this form as well.
