How to Delete a Selected Row from JTable in Java

In this tutorial, we are going to see how to delete a selected row from a JTable in Java. JTable is a subclass of JComponent class for displaying complex data structures. JTable can follow the Model View Controller (MVC) design pattern to display data in rows and columns. JTable can generate ListSelectionListener, TableColumnModelListener, TableModelListener, CellEditorListener and RowSorterListener interfaces. We can remove a selected row from a JTable by using removeRow() method of DefaultTableModel class.
