Why is it recommended to prioritize using try with resources instead of try finally

1、 Background introduction

try-with-resourcesIt is a new exception handling mechanism introduced in JDK 7, It allows developers to avoid explicit releasetry-catchResources used in statement blocks 。

For example, we take file resource copying as an example, which is familiar to everyonetry-catch-finallyWrite it as follows:

public class ResourceTest1 {    public static void main(String[] args) {
        BufferedInputStream bin = null;
        BufferedOutputStream bout = null;
        try {
            bin = new BufferedInputStream(new FileInputStream(new File( "test.txt")));
            bout = new BufferedOutputStream(new FileOutputStream(new File( "out.txt")));
            int b;
            while ((b = bin.read()) != -1) {
                bout.write(b);
            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
              //Close file stream     
            if (bin != null) {
                try {
                    bin.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            if (bout != null) {
                try {
                    bout.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}
