It is useful to have some rules for rewriting boolean expressions. Here is an easy one:
!!Ais equivalent toA
The operand A stands for a true/false value or an expression that results in a true/false value. This truth table shows the rule:
| A | !A | !!A |
|---|---|---|
| true | false | true |
| false | true | false |
Rewrite the following if statement:
if ( !(value != 399) )
System.out.println("Correct Value");
else
System.out.println("Wrong Value");
