Set Jtable/Column Renderer for booleans

Right now I have in my Jtable:

but I want to have:

Therefore ,I guess, I have to covert my trues/false’s into object like:

  Object rowData[][] = { { "1", Boolean.TRUE }, { "2", Boolean.TRUE }, { "3", Boolean.FALSE },
      { "4", Boolean.TRUE }, { "5", Boolean.FALSE }, }; 

Right now I get the data like this:

    int i=0;
    data=new Object[tupel.size()][1];
    while(i<tupel.size()){
        row=tupel.get(i);
        data[i][0]=new Boolean(row.isTrueorFalse());//my "Boolean method"
        i++;
    }
}

So my question is:

How to convert my data into Objects so that I have diplayed the ticks?

UPDATE

The isTrueorFalse Method:

public boolean isTrueorFalse() {
        return isTrueorFalse;
}

Answer 1

JTable has built_in support for Boolean value, then renderer/editor shows JCheckBox

have to override column in the XxxTableModel with proper Column Class

@Override
public Class getColumnClass(int column) {
    return getValueAt(0, column).getClass();
}
