! actually it means not, which reverses a boolean.
CORRECT QUESTION:
For the given program, how many print statements will execute?
public static void printShippingCharge(double weight) { if((weight > 0.0) && (weight <= 10.0)){ System.out.println(weight * 0.75); }
else if((weight > 10.0) && (weight <= 15.0)) { System.out.println(weight * 0.85); }
else if((weight > 15.0) && (weight <= 20.0)) { System.out.println(weight * 0.95); } }
public static void main(String args[]) {
printShippingCharge(18);
printShippingCharge(6);
printShippingCharge(25); }
Answer:
Two of the print statements will output values
Explanation:
These two calls to the printShippingCharge are the ones that will output values: printShippingCharge(18); and printShippingCharge(6);
The first if statement is true when the value of weight is 6 (weight > 0.0) && (weight <= 10.0)
The Third if statement is true when weight is 18 (weight > 15.0) && (weight <= 20.0)
NOTE: That I made correction to the variable weight. The question isn't consistent with the variable name. It used weight and itemWeight at different points this will lead to a compiller error
