Condition for Displaying Data in JTable
Description:
Displaying data from a database using JTable in Java Swing involves retrieving the data through JDBC and populating the table dynamically. Establish a connection to the database using DriverManager and create a Statement or PreparedStatement to execute the SQL query. The query results are stored in a ResultSet, which holds the data to display. To transfer the data into the JTable, use a DefaultTableModel, iterating through the ResultSet to add rows to the model. Column headers are extracted from the ResultSetMetaData and set in the table model. Finally, the JTable is created with the populated model and added to a JScrollPane to support scrolling. This approach ensures dynamic updating of the JTable based on the data retrieved from the database.
