Answer:
super("Title here");
Explanation:
JFrame is a Java swing class for displaying Frames in Graphical User Interface. The title of a JFrame can be set by calling super("Title here"); as the first statement in the constructor of your class that extends JFrame. This causes the constructor of the parent JFrame class to be called with the specified String argument and this String is then set as the title for the GUI frame.
Answer:
True.
Explanation:
In statement 1 we have loop-=++count;
which means loop = loop - (++count);
Where ++ is a pre increment operator which increases the value of count by 1 before using it.
In the other statement also we are doing the same thing.
Increasing the count by 1 and decreasing it from the loop variable.
Hence we conclude that the answer is True.
