Mass produce JTables

Question

I want to make 25 JTables. I generate the table names by doing:

for(int i=0; i < 26; i++)
{
    TableNames[i] = \"Table\" + i + \"\";
    ...

Answer 1

TableNames[i] = new JTable(model)

put inside the for loop i agree previous statement make error try this

for(i=0;i<TableNames.length();i++)
{
new JTable(TableName[i]);
}

Answer 2

Instead of an array, consider using a List<JTable> or List<TableModel>. Pass the name to the table's constructor or factory method. The example below uses the Component's name, but a JComponent's client property may be more versatile.

Update: The revised Java 8 example below illustrates how to add new tables dynamically.

import java.awt.EventQueue;
import java.awt.GridLayout;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollBar;

import javax.swing.JTable;
import javax.swing.event.ListSelectionEvent;
import javax.swing.table.DefaultTableModel;
