Answer 1

Make this modfication:
public void show()
(new IOException()).printStackTrace();to see:
java.io.IOException
     at cwdm1.show(cwdm1.java:15)
     at cwdm1.main(cwdm1.java:48)
java.io.IOException
     at cwdm1.show(cwdm1.java:15)
     at java.awt.Component.show(Unknown Source)
     at java.awt.Component.setVisible(Unknown Source)
     at cwdm1.show(cwdm1.java:31)
     at cwdm1.main(cwdm1.java:48)
java.io.IOException
     at cwdm1.show(cwdm1.java:15)
     at java.awt.Component.show(Unknown Source)
     at java.awt.Component.setVisible(Unknown Source)
     at cwdm1.show(cwdm1.java:31)
     at java.awt.Component.show(Unknown Source)
     at java.awt.Component.setVisible(Unknown Source)
     at cwdm1.show(cwdm1.java:31)
     at cwdm1.main(cwdm1.java:48)
... and so on unitl the overflow
