Need to close only the new popup window

Could anyone please help me with this.

FromMain.java, the main user interface pops up, on clickingvf2vpExebut button,vf2vpExe.java's user interface pops up. After I process thevf2vpExe.java user interface and close it even myMain.java user interface closes.

But on clicking theexitbut invf2vpExe.java, I need to close only thevf2vpExe.java user interface and notMain.java user interface also.

My code is:

Main.java

privatevoid vf2vpExebutActionPerformed(java.awt.event.ActionEvent evt)

{

try

{

vf2vpExe vf=new vf2vpExe();

vf.mainclass();

}

catch(Exception e)

{

}

}

vf2vpExe.java

privatevoid exitbutActionPerformed(java.awt.event.ActionEvent evt)

{

System.exit(0);

}
