Java array reading loop never ends? -
hi new programming , today writing code 1 java array task , in beginning tried test have done , in first loop (the array reading ) program not stop read numbers enter number (n) length. please ?
import java.util.scanner; public class readtwoelementsforarrayandsum { public static void main(string[] args) { // todo auto-generated method stub scanner in = new scanner(system.in); system.out.println("please enter n element:"); int n = in.nextint(); system.out.print("please enter k element, k < n: "); int k = in.nextint(); int[] arrayn = new int[n]; system.out.print("please enter n numbers array: "); for(int = 0; < arrayn.length; i++) { arrayn[i] = in.nextint(); } boolean changed = false; { int temp = 0; for( int = 0; < (arrayn.length-1); i++) { if(arrayn[i] > arrayn[i+1]){ temp = arrayn[i]; arrayn[i] = arrayn[i+1]; arrayn[i+1] = temp; changed = true; } } } while (changed); for(int = 0; < arrayn.length; ++) { system.out.printf("%d", arrayn[i]); system.out.print(k); } in.close(); } }
loop infinite because once if condition inside loop executed changed set true , value never changed false causing infinite loop while loop.
instead can use arrays.sort(arrayn) or if want use loop try below code
int count = 0; { int temp = 0; count++; (int = 0; < (arrayn.length - 1); i++) { if (arrayn[i] > arrayn[i + 1]) { temp = arrayn[i]; arrayn[i] = arrayn[i + 1]; arrayn[i + 1] = temp; } } } while (count < (arrayn.length));
