Detect Swing Version

Sun changed swing naming convention from com.sun.java.swing to javax.swing. This created a bit of confusion, but you can exploit it to see what version of swing is installed in a browser, or any other Java enabled environment.

 

Class swingNewJButtonClass = null;
Class swingOldJButtonClass = null;
try 
{
    swingOldJButtonClass = Class.forName("com.sun.java.swing.JButton");
    if(swingOldJButtonClass != null)
        System.out.println("Old Version of Swing installed"); 
}
catch(ClassNotFoundException e) 
{
}
try 
{
    swingNewJButtonClass = Class.forName("javax.swing.JButton");
    if(swingNewJButtonClass != null)
        System.out.println("New Version of Swing installed"); 
} 
catch(ClassNotFoundException e) 
{
}
if(swingOldJButtonClass == null && swingNewJButtonClass == null)
    System.out.println("No Version of Swing Installed");
