I fial at java

   6. The following for loop will print out the first 20 squares. Convert the for loop into a while loop.

      for(int i = 1; i <= 20; i++)
         System.out.println(i + " squared is " + i * i);



While ( I <= 20) {
  System.out.println (i + “squared is” + i * i);
  i++
       }



   7. Explain the difference between a while statement and a do-while.

The while statement continually executes a block of statements while a particular condition is true which it checks first. The difference is that do-while evaluates its expression at the bottom of the loop instead of the top



   8. Given:

      final double rate = 6.25;
      char             pass =  'P';


      True or false, the following statements are correct. If false, you must Explain!

      a)    rate  =  9.35;


False. Because the expression ‘final’ was used, rate cannot be assigned a new value. Thus it remains with its first value 6.25

      b)  pass  =  "pass";


we would have to specify that the code is a string for this to work

   9. What is the output?

      int [] X = {22,44,88};
      int [] Y = {11,33,55};
      Y = X;
      System.out.println( Y[0] );
      System.out.println( X[ X.length � 1] );

 22 and 44


is this all correct?

map (^2) [1..20]

and I fail so hard I spelled fail wrong in my opening post

Tell me about this � operator.

hmm thats weird. for some reason it pasted as �. the correct thing is

int [] X = {22,44,88};
int [] Y = {11,33,55};
Y = X;
System.out.println( Y[0] );
System.out.println( X[ X.length - 1] );

is this all correct?
actually no.

>>6
I guess my mistake is question 9

>>1
while first tests the expression then enters its body, do/while first enters the body and then tests the expression

>>7
6 and 9

number 6 should be 22 and 88

>>4
It's the binary conditional operator. In this case if X.length is true, it evaluates to 1, otherwise it evaluates to false.

6. Incomplete.
7. Could be clearer.
8a. Correct.
8b. Which 'code'? Clarify.
9. Incorrect.

I would probably give you half a point per question.
