What is the 1st step in creating a WHILE loop?

• Loop Condition

• Display Out

• Declaration of Variable

• Increment or Decrement

• 1 1 2 3 4 5 6

• 2 2 3 4 5 6 7

• 6 6 5 4 3 2 1

• 7 7 6 5 4 3 2

• 7 7 7 7 7 7 7

A while loop carries on as long as...

• The condition in the brackets is true

• The condition in the brackets is false

• i < 10

• the for loop has not ended

While loops are not really important or necessary in Java

• True

• False

else { num = 30; }

• 20

• 30

• 23

• Mail m = p[10].getBox (57) .getmail (4);

• Mail m = p[9].getBox (56).getMail(3);

• Mail m = p.geMail (57) .getMail (4) [10];

• Mail m = getMail (getBox (p[9], 560, 3)

• Mail m = new Mail (10, 57,.4);

• boolean

• bool

• Boolean

• Bool
