Java9中的Try-With-Resources语句有哪些改进
Java9改进了try-with-resources,
在下面的示例中,我们实现了“try-with-resources”的概念。
示例
import java.io.*;
public class TryWithResourceTest {
public static void main(String[] args) throws FileNotFoundException {
String line;
Reader reader = new StringReader("nhooo.com");
BufferedReader breader = new BufferedReader(reader);
try(breader) {
while((line = breader.readLine()) != null) {
System.out.println(line);
}
} catch(IOException ioe) {
ioe.printStackTrace();
}
}
}输出结果
