may kulang ka.


double amountDue = itemPrice * itemQuantity;
return amounDue;

 

[Alieson09]

public double getTotalCost() {
    return amountDue;
}

Ganito lang kasi yung value ng amountDue ay dun mo ilalagay setTotalCost()

ano ilalagay sa settotalcost??,nabago kona sa gettotalcost

Sa setTotalCost() dito mo gagawin yung operation.

public void setTotalCost(double itemPrice, int itemQuantity) {
        this.itemPrice = itemPrice;
        this.itemQuantity = itemQuantity;
        this.amountDue = this.itemPrice * this.itemQuantity;
}

Kung mapapasin mo sa tawag sa kanila dapat alam mo na yung purpose, sa getter dun mo lang kukunin yung value ng variable kaya nga get return value lang, sa setter naman dun mo iseset or ilalagay yung value kaya set.

Sa main class mo gumamit ka ng scanner, gumawa ka ng scanner instance. Stick with the instruction given na din naman yan.

Scanner s = new Scanner(System.in);

Sa readInput() nakalagay sa instruction mag lalagay ng input or sa ibang salita mag seset ka ng values dun sa mga variable. Nakuha mo naman yung idea haha mali lang yung implementation.

So sa pag set mo ng value sa variables ano yung gagamitin mo? malamang yung mga setter

public void readInput(String name, int quanti, double price) {
    setItemName(name);
    setTotalCost(price, quanti)
}

Sa writeOutput() naman display lang naman yung output. Since ok na din naman yung mga setter madali nalang yung pag display sakanila. Gagamitin mo dito yung ilang private variables at syempre yung mga getter.

public void writeOutput() {
    System.out.println("Your are purchasing " + this.itemQuantity + " " + getItemName() + " at " + this.itemPrice + " each.");
    System.out.println("Amount due is " + getTotalCost());
}

Gamitin mo yung readInput() & writeOutput() tapos alisin mo yang nasa line 15 & 16 mo. Pero gumawa ka muna ng instance nung purchase.java

Ok na yung sinend mo kanina na main.java may idadagdag nalang naman doon at may tatangglin yung line 15 & 16.
yang purchase A = new purchase() idagdag mo doon tapos gamitin mo yung readInput() at writeInput()

        System.out.println("Enter the name of the item you are purchasing: ");
        String name = s.nextLine();
        System.out.println("Enter the quantity and price separated by a space: ")
        int quantity = s.nextInt();
        double price = s.nextDouble();
       
        // insert readInput() method here.
        // insert writeInput() method here.
