java - Sorting an array of objects by two doubles -

so had delimited file read array.

array[0] boxid (double)

and

array[1] movieid (double)

i have no clue how i'd able sort array these 2 doubles. comments? i've tried looking @ other questions on website got confused them. i'm in first programming class.

movies[] newmastermovies = new movies[200];      int newmastercount = 0;     int mastercount = 0;     int updatecount = 0;      while (updatecount < updatetotalcounter || mastercount < mastertotalcounter) {          string updatecompare = updatemovies[updatecount].getboxid() + updatemovies[updatecount].getmovieid();         string mastercompare = mastermovies[mastercount].getboxid() + mastermovies[mastercount].getmovieid();         int compare = updatecompare.compareto(mastercompare);          if (compare > 0) {             newmastermovies[newmastercount] = mastermovies[mastercount];             mastercount++;             newmastercount++;         }          if (updatemovies[updatecount].getactioncode() == "a") {             newmastermovies[newmastercount] = updatemovies[updatecount];             updatecount++;             newmastercount++;         }          if (updatemovies[updatecount].getactioncode() == "d") {             updatecount++;             mastercount++;         }          if (updatemovies[updatecount].getactioncode() == "c") {             newmastermovies[newmastercount] = updatemovies[updatecount];             updatecount++;             newmastercount++;             mastercount++;         }      } 

that array looks trying sort. tried selection sort got confused since want sort 2 properties, not one.

this guy here wonders

  arrays.sort(iarr); 

here can do: here example code

 public class arraydemo {   public static void main(string[] args) {       // initializing unsorted int array      int iarr[] = {2, 1, 9, 6, 4};       // let print elements available in list      (int number : iarr) {      system.out.println("number = " + number);      }       // sorting array      arrays.sort(iarr);       // let print elements available in list      system.out.println("the sorted int array is:");      (int number : iarr) {      system.out.println("number = " + number);     }   } } 

and results should this

number = 2

number = 1

number = 9

number = 6

number = 4

the sorted int array is:

number = 1

number = 2

number = 4

number = 6

number = 9

hopes helps some
