Edit Properties with JTable

• The JTable constructor takes two arguments and creates a table of the size of your choice. The first argument is an array of the values of the table, and the second is an array of the column titles.

  
   table=new JTable(values,new String []{"Property", "Value"});
  
  

With this simple JTable constructor, any array can be put into a table. Modification to the data is much more intuitive with the GUI when aligned in a table.

• The data can be retrieved by getValueAt(int, int).

  
    propertyName=(String)table.getValueAt(i,0);
  
  

Shown below is a still image of Java application EditProperties, which uses the above function calls. The table contains the name of the properties and their values, which can be modified within each cell of the table. Press Save button when you finish the edit and the properties will be returned. Click the link below for the jar file.

In the application EditProperties above, there is one more line added to reflect the changes to the table.

• The current modification to the data will be reflected by stopCellEditing() function call.

  
    table.getCellEditor().stopCellEditing();
  
  

Please refer to Class Properties: How to Manage Class Variables page on how to save and load the property values.

Let's not reinvent the wheel. Let's explore the world that Java can offer, with its rich sets of program libraries and extendable object oriented paradigm.
