Printwriter out of servlet = response Getwriter() uses

• Java

All along, I only know that out can input data (HTML, TXT, etc.) to the client browser page. Today, I found that my understanding deviated when debugging with PHP programs. @ h_301_1@

Out is the output character stream, that is, after the servlet receives the request, the servlet uses out to return the result. No matter what the client is (browser, httpclient or other servlets, etc.), it establishes a stream output pipeline with the client, and then outputs the character stream to the requester. @ h_301_1@

I would like to record my shallowness in this text@ H_ 301_ 1@
