Question

I’ve seen reference in some C# posted questions to a ‘using’ clause. Does java have the equivalent?

Answer 1

Yes. Java 1.7 introduced the try-with-resources construct allowing you to write:

try(InputStream is1 = new FileInputStream('/tmp/foo');     InputStream is2 =  new FileInputStream('/tmp/bar')) {          /* do stuff with is1 and is2 */ } 

… just like a using statement.

Unfortunately, before Java 1.7, Java programmers were forced to use try{ … } finally { … }. In Java 1.6:

InputStream is1 = new FileInputStream('/tmp/foo'); try{      InputStream is2 =  new FileInputStream('/tmp/bar');     try{          /* do stuff with is1 and is 2 */      } finally {         is2.close();     } } finally {     is1.close(); }
