    Question Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException

    Hi everyone, I'm a beginner in Java and I'm trying to divide a Jtable into two auther Jtables.Thank you for your help.
     public String Ex(JTable table, JTable tab2, JTable tab3) {
            String message = "Erreur";
            DefaultTableModel modele = new DefaultTableModel();
            tab2.setModel(modele);
            DefaultTableModel modele1 = new DefaultTableModel();
            tab3.setModel(modele1);
            int NumeroLigne = table.getRowCount(), NumeroColonne = table.getColumnCount();
            int t = 0;
            if (NumeroLigne-1 % 2 == 0) {
                t = NumeroLigne / 2;
            }
            else{
                t=(NumeroLigne/2)+1;}
            for (int i = -1; i < t; i++) {
               int r=0;
               r=i+1;
                Object Row[]=new Object[r];
                modele.addRow(Row);
                for (int j = 0; j < NumeroColonne; j++) {
                    if (i ==-1) {
                        modele.addColumn(String.valueOf(table.getColumnName(j)));
                    } else {
                        modele.setValueAt(table.getValueAt(i, j), i, j);
                }
            }}
            for (int i = t; i < NumeroLigne; i++) {
                Object Row1[]=new Object[i];
                modele1.addRow(Row1);
                for (int j = 0; j < NumeroColonne; j++) {
                    if (i ==t) {
                        modele1.addColumn(String.valueOf(table.getColumnName(j)));
                    } else {
                       for(int r=1;r<NumeroLigne;r++){
                        modele1.setValueAt(table.getValueAt(i,j), i, j);
                       }
                    }

    There error says that an index was used past the end of the array. Look at the line where that exception happened and find the array that was being indexed see why there was an index value past the end of the array.
    If you don't understand my answer, don't ignore it, ask a question.

    from what I understood in your post, in line 34 modele1.setValueAt(table.getValueAt(i,j), i, j);
    I'm asking to put the value table[11][0] in a modele1[11][0] which doesn'texist yet,I have to change the line 27 28 Object Row1[]=new Object[i];
    modele1.addRow(Row1);

    line 34 modele1.setValueAt(table.getValueAt(i,j), i, j);
    What is the size of table and the size of modele1 and what are the values in i and j when that statement is executed?

    Talking Re: Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException

    I find a solution, I just creat model with enough place then stated to fill the model and I changed the pool for with while, add two different counter one for the model and one for the table, I also made some modifications so that it can work in the right way. I just needed to understand the error message, thanks for your help.
    ps: If you want I can post the correct code.
