Frame f1 = new frame(); f1.setDefaultCloseOperation(int); so, this is the correct answer.

If a class implements an interface then it is necessary for that class to define body to all the methods defined in the interface it is implementing. But, windowMoved() method is not present in windowListener interface. So, when a class will implement this interface this method need not to be define in the class. So, this option is correct.

These are:- lowLayout():- create a default flowLayoutFlowLayout(int Alignment):- creates a flowlayout with specified alignment, where alignment can take value, FlowLayout.LEFT, FlowLayout.LEFT ,FlowLayout.LEFTFlowLayout(int alignment , int hgap, int vgap):- same as second constructor with specified horizontal and vertical gap between the components. So, this answer is correct.
