JTable Class In Java

JTable Class
 
In Java, JTable class displays the data on two dimensional tables of cells.
 
Constructors of JTable class

JTable()

This constructor creates a table with the empty cells.
 
JTable(Object[][] rows, Object[] columns)

This constructor creates a table with the specific data.
 
Let’s see an example of JTable class, given below.
 
Code
  1. import javax.swing.*;  
  2. public class JTableExample {  
  3.     JFrame jf;  
  4.     JTableExample() {  
  5.         jf = new JFrame();  
  6.         String data[][] = {{"161", "Bob", "6000"},  
  7.         {"125", "Mai", "8000"},  
  8.         {"121", "Sam", "7000"}};  
  9.         String column[] = {"ID", "NAME", "SALARY"};  
  10.         JTable jt = new JTable(data, column);  
  11.         jt.setBounds(30, 40, 200, 300);  
  12.         JScrollPane sp = new JScrollPane(jt);  
  13.         jf.add(sp);  
  14.         jf.setSize(400, 400);  
  15.         jf.setVisible(true);  
  16.     }  
  17.     public static void main(String[] args) {  
  18.         new JTableExample();  
  19.     }  
  20. }  
  21.

Summary

Thus, we learnt that the JTable class displays the data on the two dimensional tables of the cells and also learnt how to use it in Java.
