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.

Can you help me with these AP Computer Science Questions. (THIS IS DUE BY 1:30 PM today) you have to evaluate the Boolean Expres

vfiekz [6]

Answer + Explanation:

'and' -> both statements are 'True' to evaluate as 'True'.

'or' -> at least one statement is 'True' to evaluate as 'True'.

1. True (grade has the value of 82, so the statement evaluates to 'True').

2. True (Both statements are true, this expression evaluates to 'True').

3. False (Both statements are false, this expression evaluates to 'False').

4. True (the != operator means not equal. Since the 'name' variable holds the string 'Rumpelstiltskin', name != 'Rumpelstiltskin' evaluates to 'False'. The 'not' operator returns the opposite of the given Boolean expression, so this expression evaluates to 'True').

5. True (name == 'Rumpelstiltskin' evaluates to 'True', so this expression is true).

6. False (All statements evaluate to 'False').

7. True (All statements evaluate to 'True').

8. False (All statements evaluate to 'True' except for not(x == - 3) which evaluates to 'False', so the whole statement now becomes false).

9. True (grade+5 < 90 and grade >= 80 evaluates to 'True', so this whole expression becomes true).

10. True (grade > 0 and x % 2 == 1 evaluates to 'True')

Hope this helps :)

At the Data Link Layer of the OSI Model, what type of address is used to identify the receiving host?

Natalka [10]

Answer:

Mac Address

Explanation:

The MAC address or Media Access Control is a unique identifier that each manufacturer assigns to their devices that can connect to the network. They consist of 48 bits in hexadecimal form, grouped into 12 pairs of characters and each character is formed by four binary numbers, generally separated by a colon. MAC addresses are used in the data link layer of the OSI model, specifically in the lower Medium Access Control layer. An example of a MAC address could be:

10: 68: c5: 5e: 27: 3f.
