A good answer might be:

5 > 2 || 12 <= 7   T  
5 > 2 && 12 <= 7   F  
3 == 8 || 6 != 6   F  
3 == 8 && 6 != 6   F  

NOT

x!x
truefalse
falsetrue

The NOT operator in Java is this: ! --- exclaimation point. The NOT operator changes true to false and false to true, as seen in the table. This may seem like a silly thing to do, but often it is useful. Sometimes it is more natural to express a condition in a particular way, but the program logic calls for the reverse of what you have written. Time for the NOT opperator.


Say that you are shopping for a new computer. You want more than 400 MHz and more than 32 Meg of RAM. Here is s program fragment:

if (  ______(speed > 400 && memory > 32)  )
  System.out.println("Reject this computer");
else
  System.out.println("Acceptable computer");
As it is written, the program is wrong: a computer that exceeds your requirements will be rejected.

QUESTION 21:

Fill in the blank so that the program fragment is correct.
