In Java, the try-with-resources statement is used to manage resources that are used in a block of code. A resource is an object that must be closed after use, such as a file, database connection, or network socket.

The try-with-resources statement ensures that a resource is closed when the block of code exits, whether normally or due to an exception. The syntax for try-with-resources is as follows:

try (ResourceType resource1 = new ResourceType();
     ResourceType resource2 = new ResourceType()) {
    // code that uses resource1 and resource2
} catch (ExceptionType ex) {
    // code to handle exceptions
}

In this syntax, ResourceType is the type of resource that you want to manage, and resource1 and resource2 are variables that refer to instances of ResourceType. The try block initializes the resources using the new operator, and then uses them in the code.

When the try block completes, the close() method is called on each resource in reverse order of their creation, releasing any resources they were using.

Here's an example of using try-with-resources to manage a file:

try (FileReader fileReader = new FileReader("example.txt");
     BufferedReader bufferedReader = new BufferedReader(fileReader)) {
    String line = bufferedReader.readLine();
    while (line != null) {
        System.out.println(line);
        line = bufferedReader.readLine();
    }
} catch (IOException ex) {
    System.out.println("An error occurred: " + ex.getMessage());
}

In this example, the try block creates a FileReader and a BufferedReader to read from a file. The BufferedReader is used to read lines from the file, and the System.out.println() method is used to print each line to the console. When the try block completes, the close() method is called on both the FileReader and the BufferedReader.

If an exception is thrown while the try block is executing, the catch block handles the exception, and then the close() method is called on the resources before the exception is propagated.
