java - Sorting an Array of int using BubbleSort -


why printed out array not sorted in below code?

public class bubblesort {     public void sortarray(int[] x) {//go through array , sort smallest highest       for(int i=1; i<x.length; i++) {          int temp=0;          if(x[i-1] > x[i]) {             temp = x[i-1];             x[i-1] = x[i];             x[i] = temp;          }       }    }     public void printarray(int[] x) {       for(int i=0; i<x.length; i++)         system.out.print(x[i] + " ");    }     public static void main(string[] args) {       // testbubblesort       bubblesort b = new bubblesort();       int[] num = {5,4,3,2,1};       b.sortarray(num);       b.printarray(num);       } }

you need 2 loops implement bubble sort .

sample code :

public static void bubblesort(int[] numarray) {      int n = numarray.length;     int temp = 0;      (int = 0; < n; i++) {         (int j = 1; j < (n - i); j++) {              if (numarray[j - 1] > numarray[j]) {                 temp = numarray[j - 1];                 numarray[j - 1] = numarray[j];                 numarray[j] = temp;             }          }     } }

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
