Class TryStmt

java.lang.Object

com.github.javaparser.ast.Node

com.github.javaparser.ast.stmt.Statement

com.github.javaparser.ast.stmt.TryStmt

All Implemented Interfaces:

Observable, Visitable, HasParentNode<Node>, Cloneable

public final class TryStmt
extends Statement

The try statement.

 try (InputStream i = new FileInputStream("file")) {
   // do things
 } catch (IOException e) {
   e.printStackTrace();
 } finally {
   System.out.println("Finally!!!");
 }
 

In this code, "i" is a resource, "// do things" is the content of the tryBlock, there is one catch clause that catches IOException e, and there is a finally block.

All of these are optional, but they should not all be empty or none at the same time.
