Question

I am having a problem with my code. Here are the relevant parts.

The method priceNow is supposed to take as an input a string in the form "Q1'20" (for example) and calculate the new price knowing that the price of the CPU decreases by 2% every quarter.

Here is my class definition code:

public class CPUv2 {
   private String launchDate;
   public CPUv2() {
       this.CPUGeneration = 1;
       this.CPUSeries = "i3";
       this.suggestedPrice = 117;
       this.CPUSpeed = 2.93;
       this.launchDate = "Q1’10";
       this.SGX = false;
   }
   public double priceNow(String sQuarterYear) {
  
       int currQuarter = Integer.parseInt(sQuarterYear.charAt(1) + "");
   int launchQuarter = Integer.parseInt(launchDate.charAt(1) + "");
       int launchYear = Integer.parseInt(launchDate.split("'")[1]);
   int currYear = Integer.parseInt(sQuarterYear.split("'")[1])
   int totalQuarter;
   if (currYear > launchYear) {

   totalQuarter = 4 * (currYear - launchYear) + (currQuarter - launchQuarter);
   } else if (currYear < launchYear) {

   totalQuarter = 0;
   } else {

   totalQuarter = currQuarter - launchYear;
   }
   double price = suggestedPrice - suggestedPrice * totalQuarter * .02;
   //applying the condition that the depriciated price cant be less than 0
   if (price>=0) {
         
   return (price);
   }
   else {
       return 0;
   }
   }
  

}

here is my driver (tester) code:

public class CPUv2Testing {
  
   public static void main(String[] args) {
       CPUv2 cpu1 = new CPUv2();
       System.out.println(cpu1.priceNow("Q3'20"));
      
}

}

the error i am getting is when i call the priceNow method in the class, but i cant figure out why.

Any help would be appreciated!

The answer to this question is as follows:

The modified code is as follows:

public class CPUv2 {
private String launchDate;
//The modified code is as follows
private int CPUGeneration;
private String CPUSeries;
private int suggestedPrice;
private double CPUSpeed;
  
private boolean SGX;
public CPUv2() {
//Here if you use the keyword this then u need to declare the variable along with its type
this.CPUGeneration = 1;
this.CPUSeries = "i3";
this.suggestedPrice = 117;
this.CPUSpeed = 2.93;
this.launchDate = "Q1'10";
this.SGX = false;
}
public double priceNow(String sQuarterYear) {
  
int currQuarter = Integer.parseInt(sQuarterYear.charAt(1) + "");
int launchQuarter = Integer.parseInt(launchDate.charAt(1) + "");
int launchYear = Integer.parseInt(launchDate.split("'")[1]);
//Here you missed semicolon for the below statement
int currYear = Integer.parseInt(sQuarterYear.split("'")[1]);
int totalQuarter;
if (currYear > launchYear) {

totalQuarter = 4 * (currYear - launchYear) + (currQuarter - launchQuarter);
} else if (currYear < launchYear) {

totalQuarter = 0;
} else {

totalQuarter = currQuarter - launchYear;
}
double price = suggestedPrice - suggestedPrice * totalQuarter * .02;
//applying the condition that the depriciated price cant be less than 0
if (price>=0) {

return (price);
}
else {
return 0;
}
}
  

}

//here is my driver (tester) code:

public class CPUv2Testing {
  
public static void main(String[] args) {
CPUv2 cpu1 = new CPUv2();
System.out.println(cpu1.priceNow("Q3'20"));
  
}

}

The output screen is as follows:
