try-catch语法结构-java课件合集
The Java try-with-resources statement is a new feature in Java SE 7 that allows you to declare resources that will be automatically closed at the end of the statement. The syntax is as follows:
```
try (resource1; resource2; ... ) {
// code that uses the resources
} catch (Exception e) {
// exception handling code
}
```
Here, `resource1`, `resource2`, etc. are the resources that need to be closed at the end of the statement. These resources should implement the `AutoCloseable` interface, which has a single method `close()` that is called to release any resources that the object is holding.
The try-with-resources statement is useful for managing resources that need to be explicitly closed, such as file streams, database connections, network connections, etc. By using the try-with-resources statement, you can avoid the need for explicit `finally` blocks to close these resources, and ensure that they are always properly closed, even in the event of an exception.
