In Java 9, the Try-with-resources statement has been improved. If we already have a resource that is final or equivalent to a final variable, then we can use that variable in the try-with-resources statement without declaring a new variable in the try-with-resources statement .
We can declare multiple resources in the try block. The try initialization block can have any number of resources, which can be null or non-null.
In the following example, we can declare multiple resources in the try-with-resources statement.
Example
import java.io.BufferedReader; import java.io.IOException; import java.io.Reader; import java.io.StringReader; public class MultipleResourcesTest { public static void main(String args[]) throws IOException { System.out.println(readData("test")); } static String <strong>readData</strong>(String message) throws IOException { <strong>try</strong>(Reader inputString = new StringReader(message); BufferedReader br = new BufferedReader(inputString)) { return br.readLine(); } } }
Output
<strong>test</strong>
