public final class TryStmt extends Statement
try { // ... } catch (IOException e) { // ... } finally { // ... }In this code, "// do things" is the content of the tryBlock, there is one catch clause that catches IOException e, and there is a finally block.
The catch and finally blocks are optional, but they should not be empty at the same time.
try (InputStream i = new FileInputStream("file")) { // ... } catch (IOException|NullPointerException e) { // ... } finally { // ... }Java 7 introduced two things:
try (r) { // ... } catch (IOException|NullPointerException e) { // ... } finally { // ... }Java 9 finishes resources: you can now refer to a resource that was declared somewhere else. The following types are allowed:
CatchClause
,
IntersectionType
,
FieldAccessExpr
,
NameExpr
Node.ObserverRegistrationMode, Node.Parsedness
ABSOLUTE_BEGIN_LINE, ABSOLUTE_END_LINE, NODE_BY_BEGIN_POSITION, prettyPrinterNoCommentsConfiguration
