what is the use java "out" object

You would have to provide more context - like what 'out' object you are talking about.

However, in general, I would assume any 'out' object would be used to write 'output' to. What output and where it goes depends on context.

- If you are talking about System.out then "out" is

static object of PrintStream class << Has a relationship with System class>> which is being used to write output on console.

- If "out" is JSP implicit object then its JspWriter object which has been provided by JSP container automatically and being used to write output on web-browser.
