How to enter the values in JTable in runtime

Question

how to enter the values in JTable in runtime

Answer 1

Basically you need a vector of vectors or an array of arrays. Example (off the top of my head):
With Arrays
String[] cols = { "colone", "coltwo", "colthree", "colfour", "colfive" };
String[] numbers = { "one", "two", "three", "four", "five" };
String[] letters = { "A", "B", "C", "D", "E" };
String[][] data = { numbers, letters };
//make sure that the table has a scroll pane wrapped around it otherwise the header is not displayed
JScrollPane scroll = new JScrollPane(new JTable(data, cols));
With Vectors
Vector cols = new Vector();
cols.addElement("colone");
cols.addElement("coltwo");
cols.addElement("colthree");
cols.addElement("colfour");
cols.addElement("colfive");
Vector numbers = new Vector();
numbers.addElement("one");
numbers.addElement("two");
numbers.addElement("three");
numbers.addElement("four");
numbers.addElement("five");
Vector letters = new Vector();
numbers.addElement("A");
numbers.addElement("B");
numbers.addElement("C");
numbers.addElement("E");
numbers.addElement("F");
Vector data = new Vector();
data.addElement(numbers);
data.addElement(letters);
//make sure that the table has a scroll pane wrapped around it otherwise the header is not displayed
JScrollPane scroll = new JScrollPane(new JTable(data, cols));The array or vector can be easily populated at runtime.
