Create a java array by reading from a file -

i have started learning java , trying read names text file created. want program ask user name , check if name in list. however, having trouble working arrays first trying read names , store them in array. here have done far.

import java.util.scanner; import java.io.file; import java.io.filenotfoundexception;   public class readnames {         public static void main(string[] args) throws filenotfoundexception         {             file file=new file("names.txt");             scanner my_input = new scanner(file);             int i=0;              string[] names = new string[20] ;              while(my_input.hasnext() && !names.equals("-1"))              {                  names[i]=my_input.nextline();                 i++;             }              my_input.close();             system.out.println(names[i]);         } } 

    public static void main(string[] args) throws filenotfoundexception {             file file = new file("names.txt");             scanner my_input = new scanner(file);              arraylist<string> names = new arraylist<>();              while (my_input.hasnext()) {                  string t =my_input.nextline();                  if( !t.equals("-1"))                  names.add(t);              }               system.out.println("enter name");             string nametocheck = my_input.nextline();             if (names.contains(nametocheck)) {                 system.out.println("found");             }             my_input.close();         } 

i'd suggest use arraylist<> because file may contain more 20 names

with normal arrays

public static void main(string[] args) throws filenotfoundexception {         file file = new file("names.txt");         scanner my_input = new scanner(file);          string[] names = new string[20];         int = 0;         while (my_input.hasnext()) {              string t =  my_input.nextline();              if(!t.equals("-1"))              names[i++] = t;         }           system.out.println("enter name");         string nametocheck = my_input.nextline();         (string temp : names) {             if (temp.equals(nametocheck)) {                 system.out.println("found");             }         }         my_input.close();     }
