Not quite sure what I should tag as [CODE]
Error reads as follows: variable numHammers might not have been initialized
totalCost = (numHackSaws*HA CKSAW_COST) + (numHammers*HAM MER_COST) +
I am only trying to determine if user put an int when asked for number of 2nd item.
I have never used any of the scanner methods to check validation of inputLeave a comment:

To use hasNextInt() in scanner class to validate input do I have to add in a range check for this to work.Leave a comment:

I got 5 Items that user inputs amount of product he or she wants, only trying to determine if user enters an int when entering number for second product. I have been searching all over net for examples. I am sure I am missing something simple. I get an error saying numHammers not intailized. Puzzeled. Here is my input of code.
System.out.prin t("How many Hacksaws? ");
numHackSaws = input.nextInt() ;...Leave a comment:

Using hasNextInt()
Trying to code in hasNextInt() for data type checking. Basicall my code ask user for input and if user doesn't use an int they get an error. I know i should have a if and else statement with this.
I am trying this data type checking in this block of code and I get tons of errors
while (isValid==false )
}
System.out.prin t("How many Hammers? ");
if(input.hasNex tInt())... -
New to Java, my teacher has confused me with detail line
In a program with parent and child classes she has asked me to print a detail line with 3 objects. Line should print name, type of object "which is a toString()", total of tuition and books. Is this the the same as I have been doing like:
ScholarshipStud ent student 1 = new ScholarshipStud ent ( "", "Joe", etc, etc.)
then later I will create this to print in output.
