org.codehaus.groovy.ast.stmt.TryCatchStatement

```
public class TryCatchStatement
extends Statement
```
Represents a try { ... } catch { ... } finally { ... } statement in Groovy. A try-catch statement combines exception handling with optional resource management (try-with-resources). It contains a main try block, zero or more CatchStatements for exception handlers, an optional finally block, and optional resource declarations that implement AutoCloseable.
