Can't construct a JTable with int[][] and String[] arguments

Question

The constructor JTable is giving me an error that says:

"The constructor JTable(int[][], String[]) is undefined"

although it has a constructor JTable(Object[][], Object[]) (Calcul.apartements is of the type int[][])

    String[] colonnes = {"Appartements", "Prix Milion de Cts", "Tempd duTrajet/C.v (en min)", "Superficie (en m2)", "Etage"};
    table  = new JTable(Calcul.appartements, colonnes);

int is not an Object. Either trying defining the array as Object[][] and put ints into it or use Integer[][] instead — MadProgrammer

@AJNeufeld What I intended to say and what my fingers said seem to be at odds far to often :P — MadProgrammer

You have two choices:

alter your Calcul.appartements data to be Object[][] or Integer[][] (as mentioned by @MadProgrammer in the comments)
Implement your own table model.

Implementing the table model might be as simple as:

TableModel dataModel = new AbstractTableModel() {
        public int getColumnCount() { return colonnes.length; }
        public String getColumnName(int col) { return colonnes[col]; }
        public int getRowCount() { return Calcul.appartements.length; }
        public Object getValueAt(int row, int col) { Calcul.appartements[row][col]; }
    };
JTable table = new JTable(dataModel);
