url - In Java, how do I set a progress bar for FileChannel? -

for example,

channels.newchannel(url.openstream());

this 1 line opens stream , gets data it, there no way can find progress it.

is there way so?

this 1 line opens stream , gets data it

no, won't until .read() it. therefore...

is there way so?

yes there is. .read(buf) buf bytebuffer.

just grab buffer's .position().

(and note channels.newchannel(inputstream) not return filechannel readablebytechannel)
