Hiding a Frame. How To?

How can i hide a frame(jframe) on runtime? (without closing the frame).

Try

public void setVisible(boolean b)
Shows or hides this component depending on the value of parameter b.
Parameters:

Use setVisible method.

For Instance :

JFrame jf=new JFrame("Test");
jf.setVisible(true) //Will Show
jf.setVisible(false) //will Hide
