-----Code------
private void CalculateSC(ActionEvent event)
{
    if(amount < 10){
        chargeAmount = 1;
    }else if((amount > 10) && (amount < 100)){
        chargeAmount = (amount * 0.1);
    }else if((amount > 100) && (amount < 1000)){
        chargeAmount = 5 + (amount * 0.05);
    }else{
        chargeAmount = 40 + (amount * 0.01);
    }

-----Requirements-----

Part I (Coding Assignment) : Calculate the Service Charge - with GUI We would like to assess a service charge for cashing a check. The service charge depends on the amount of the check. Business Rules/Criteria: If the check amount is less than $10, we will charge $1. If the amount is greater than or equal to $10 but less than $100, we will charge 10% of the amount. If the amount is greater than or equal to $100, but less than $1,000, we will charge $5 plus 5% of the amount. If the value is over $1,000, we will charge $40 plus 1% of the amount. Display a pie chart that displays the % of checks cashed that are: less than $10 greater than or equal to $10 and less than $100 greater than or equal to $100 and less than $1000 greater than or equal to $1000 Other Requirements: GUI Notes: Capture check amount from user input (use a GUI text box) Use labels where needed to prompt user Display total in label Use a button to: Calculate the current check amount, service charge and the total, then Display graph with current % information Note: Use a multibranch if-else statement to compute the service charge. Note: Keep track of the current % amounts (continue to calculate total %)

Answer 1

Code:

import javax.swing.JOptionPane;
public class a {

public static void main(String[] args) {
String amountStr;
double amount,serviceCharge,total;
  
amountStr = JOptionPane.showInputDialog("Enter cheque amount: ");
amount = Double.parseDouble(amountStr);
  
serviceCharge = CalculateSC(amount);
total = amount + serviceCharge;
JOptionPane.showMessageDialog(null, "Cheque Amount : " + amount + "\nService Charge : "+serviceCharge+"\nTotal : "+total, "Results", JOptionPane.PLAIN_MESSAGE );
  
System.exit(0);
  
}
private static double CalculateSC(double amount)
{
double chargeAmount=0;
if(amount < 10){
chargeAmount = 1;
}else if((amount > 10) && (amount < 100)){
chargeAmount = (amount * 0.1);
}else if((amount > 100) && (amount < 1000)){
chargeAmount = 5 + (amount * 0.05);
}else{
chargeAmount = 40 + (amount * 0.01);
}
return chargeAmount;
}
}

Output:
