java - An array in main reffering to an array outside main -

i'm trying create array in main making identical array created in method outside main. cant think of way this...

here's code:

public class grid {          public void creategrid() {         int n = stdin.readint();         int thisarray[][] = new int[n][n];         (int x = 0; x < n; x++) {             (int y = 0; y < n; y++) {                 int n = (int) (math.random() * 6 + 1);                 thisarray[x][y] = n;                             }         }      }     public static void main(string []args){              grid g = new grid();         int [][] newarray = //thisarray      } } 

are looking answer? have changed return type of method int[][] , inside main method can call creategrid method int[][]

public class grid {          public int[][] creategrid() {         int n = stdin.readint();         int thisarray[][] = new int[n][n];         (int x = 0; x < n; x++) {             (int y = 0; y < n; y++) {                 int n = (int) (math.random() * 6 + 1);                 thisarray[x][y] = n;                             }         }         return thisarray;      }     public static void main(string []args){              grid g = new grid();         int [][] newarray = g.creategrid();     } } 

if want newarray on basis of n send n creategrid method. have add 1 parameter in creategrid method given below. remove stdin.readint() creategrid method

public class grid {          public int[][] creategrid(int n) {         int thisarray[][] = new int[n][n];         (int x = 0; x < n; x++) {             (int y = 0; y < n; y++) {                 int n = (int) (math.random() * 6 + 1);                 thisarray[x][y] = n;                             }         }         return thisarray;      }     public static void main(string []args){              grid g = new grid();         int [][] newarray = g.creategrid(stdin.readint());  //new array everytime on basis of input value.     } }
