java - JOptionPane getValue method -

i started studying java in college. , in online test, allowed search, had doubt method getvalue available in class joptionpane. true method returns object of class string? if not, why? kind of object method returns? please answer me. thank you.

it depends on joptionpane , value put there selected. if program gives user choice between several strings (choose: "dog", "cat"...) can expect string when calling getvalue() method.

but careful, getvalue() returns object class object , not string. object the mother of classes, , joptionpane can hold want (string, integer, images other joptionpanes...) method getvalue() can't sure of kind of class returning. that's why returning object of class object.

if sure joptionpane contains string use this:

   string mystring = (string) myjoptionpane.getvalue(); 

if not 100% sure, test result first:

   if( myjoptionpane.getvalue() instanceof string){        string mystring = (string) myjoptionpane.getvalue();    } 

now if wondering why question got voted down: may want google questions first. first way in java docs. example here description of joptionpane.getvalue(). don't confused complex looking docs. give correct answer want know how methods , classes work.
