This may help you. 

        Dimension d = new Dimension(900, 800);
        tbl_transaction.setAutoResizeMode(tbl_transaction.AUTO_RESIZE_OFF);
        tbl_transaction.setPreferredSize(d);
        tbl_transaction.setPreferredScrollableViewportSize(d);

To prevent that all columns are resized to the ScrollPane size you can disable the auto resize:

table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);

Adding your ScrollPane to the center of the BorderLayout should set the maximum size to the screen size, because normally the JFrame can't become bigger.

To set the size of the ScrollPanes ViewPort to the screen size you can use the awt Toolkit.

table.setPreferredScrollableViewportSize(Toolkit.getDefaultToolkit().getScreenSize());

Add your JTable inside JScrollPane and set for scrollbars.

new JScrollPane(table, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED, JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);

Code sample for JTable to fit the screen size 

public class TestJTableFitsScreenWidth {

    public static void main(String... args) {
        SwingUtilities.invokeLater(new Runnable() {

            public void run() {
                JFrame f = new JFrame();
                DefaultTableModel dtm = new DefaultTableModel(
                        new String[][]{
                            new String[] {"A", "B", "D"},
                            new String[] {"D", "E", "F"}
                        },
                        new String[] {"col1", "col2", "col3"});
                JTable table = new JTable(dtm);
                table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
                f.getContentPane().setLayout(new BorderLayout());
                f.getContentPane().add(table, BorderLayout.CENTER);
                f.setVisible(true);
                f.pack();
            }
        });
    }
}
