java - Scanning a text file -


it simple question. have problem scanning text file. want scan text file , show message in joptionpane. scans shows first line of text file , stops disregarding other lines. if can little help. thank much! here code:

file file = new file("src//mytxt.txt");            try{                scanner input = new scanner(file);                while(input.hasnext()){                    string line = input.nextline();                    joptionpane.showmessagedialog(null, line);                    return;                        }                input.close();            }            catch (filenotfoundexception ex) {                joptionpane.showmessagedialog(null, "file not found");            }         }

using while (input.hasnext()) { // scan , append each line string variable

}`

scan each line file , keep whole text in string variable. use joptionpane.showmessagedialog(null,op) show whole text in single joptionpane.
