Add a title to a JTable

Question

I have a JTable which is created using a TableModel JTable t = new JTable(tableModel) I want to add a title to it. I was hoping for something like t.setTi

You would have to add it when you instantiate your DefaultTableModel:

String data[][] = {{"Vinod","MCA","Computer"},
{"Deepak","PGDCA","History"},
{"Ranjan","M.SC.","Biology"},
{"Radha","BCA","Computer"}};

String col[] = {"Name","Course","Subject"};

DefaultTableModel model = new DefaultTableModel(data,col);
table = new JTable(model);

If it already exists, you can do something like this:

ChangeName(table,0,"Stu_name");
ChangeName(table,2,"Paper");

public void ChangeName(JTable table, int col_index, String col_name){
    table.getColumnModel().getColumn(col_index).setHeaderValue(col_name);
}
