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(itemWeight * 0.85); } else if((weight > 15.0) && (weight <= 20.0)) { System.out.println(itemWeight * 0.95); } } public static void main(String args[]) { printShippingCharge(18); printShippingCharge(6); printShippingCharge(25); }

Answer 1

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
