java - I get [Ljava.lang.Object;@ instead of data on my JTable -

am trying fill jtable form existing object[][][] array problem data or containing [ljava.lang.object;@ instead of (integer) data though mad system.out.println("") print data before putting them jtable same problem ; here code next small shot screen , thanx help.

import java.awt.component; import javax.swing.jframe; import javax.swing.jscrollpane; import javax.swing.jtable;  public class gass extends jframe {   string title[] ={"box", "weight", "priority"};      public gass() {         int nb=interface1.bnumber;         object[][][] data = new object[nb][nb][nb];         int e1=0, e2=0;  (int i=0;i<nb;i++)             {       data[i][0][0] = i+1;                     e1 = (int) (math.random() * 100);                     data[0][i][0] = e1;                     e2 = (int) (math.random() * 10);                     data[0][0][i] = e2;                                }   (int j=0;j<nb;j++)               {                      system.out.println("*"+data[j][0][0]+"*"+data[0][j][0]+"*"+data[0][0][j]+"*");               }               jtable table = new jtable(data, title);        component add = this.getcontentpane().add(new jscrollpane(table));        this.setvisible(true);        table.setpreferredscrollableviewportsize(table.getpreferredsize());        this.setsize(800,400); } } 

another problem wrong data in first cases of object array ***data[0][0][0] = wrong information !!*** next, link description of output of small application , lot help

click in link here description image

the jtable constructor takes object[][] argument.

this array array of rows. data[i] row, array of columns.

and each row in array array of columns. each column (data[i][j]) should contain data displayed in 1 cell of jtable.

in case, data array. since there no specific renderer associated object arrays, tostring() method of array used display array in cell. , array's tostring() method returns [ljava.lang.object;@.

you should tell display in each cell, better answer, explaining should do.

edit:

given want display, need two-dimensional array:

object[][] data = new object[nb][3]; // nb rows, 3 columns (int row = 0; row < nb; row++) {     data[row][0] = row + 1; // first column: row number     data[row][1] = math.random(100); // second column: weight     data[row][2] = math.random(10): // third column: priority }
