java - Can we use the Lambda Expression for WindowListener? if yes how? if no why? Can i set the Lambda Expression for the below code snippet? -
this question has answer here:
this.addwindowlistener(new windowadaptor(){ public void windowclosing(windowevent we) { system.exit(0);//to close window } });
this request, please make code using lambda expression.
a lambda expression can substitute functional interface (i.e. interface single non default method). therefore windowadapter, has multiple methods (windowactivated(windowevent e)
, windowclosed(windowevent e)
, windowclosing(windowevent e)
, ...), can't substituted lambda expression.
