java - Trouble with splitting an array into chunks -

i have array:

private static int[] array = {5, 2, 1, 6, 3, 7, 8, 4}; 

i'm trying split two-dimensional array x amount of chunks, of chunks have equal length (in case, 2), assign each value of original array corresponding index within array. increment index of chunk number , reset index iterating through individual arrays hit length of one.

problem is, code wrote perform isn't outputting anything:

public class debug  {      private static int[] array = {5, 2, 1, 6, 3, 7, 8, 4};       private static void chunkarray(int chunksize)       {          int chunknumindex = 0;          int chunkindex = 0;          int numofchunks = (int)math.ceil((double)array.length / chunksize);          int[][] twodimensionalarray = new int[numofchunks][chunksize];           (int = 0; < array.length; i++)          {              twodimensionalarray[chunknumindex][chunkindex] = array[i];              chunkindex++;               while(chunknumindex < numofchunks)              {                  if (chunkindex == chunksize)                  {                      chunknumindex++;                      chunkindex = 0;                  }              }          }           for(int = 0; < chunknumindex; i++)          {              for(int j = 0; j < chunkindex; j++)              {                  system.out.printf("%5d ", twodimensionalarray[i][j]);              }               system.out.println();          }      }       public static void main(string args[])      {          chunkarray(2);      }   } 

could of assistance in debugging program?

the problem have unnecessary while(chunknumindex < numofchunks) makes no sense. if statement sufficient iterate variables correctly:

    (int = 0; < array.length; i++) {         twodimensionalarray[chunknumindex][chunkindex] = array[i];         chunkindex++;         if (chunkindex == chunksize) {             chunknumindex++;             chunkindex = 0;         }     } 

also, remember values of chunknumindex , chunkindex dynamic, last loops, use twodimensionalarray.length , twodimensionalarray[0].length instead:

    for(int = 0; < twodimensionalarray.length; i++) {         for(int j = 0; j <  twodimensionalarray[0].length; j++) {             system.out.printf("%5d ", twodimensionalarray[i][j]);         }     }
