hello,
So, the question is asking to take two numerical inputs from the user and display sum , difference and product of those inputs.
To display sum - call the function "calculateSum" and simply return the addition of the numbers(which was recieved as parameters) to the calling function.
To display difference - call the function "calculateDifference" and simply return the difference of the numbers(which was recieved as parameters) to the calling function.
To display difference - call the function "calculateProduct" and return the product of the numbers(which was recieved as parameters) to the calling function.
To display the output - we are inserting the results we have got from the above functions in the message dialog of JOptionPane.
As an example , please the below code : -
public class Computation {
public static void main(String []args){
double value1;
String value1String;
double value2;
String value2String;
value1String=JOptionPane.showInputDialog("Enter first numeric value : ");
value1=Double.parseDouble(value1String);
value2String=JOptionPane.showInputDialog("Enter second numeric value : ");
value2=Double.parseDouble(value2String);
double sum=calculateSum(value1,value2); // call to calculate sum
double difference=calculateDifference(value1,value2); // call to calculate difference
double product=calculateProduct(value1,value2); // call to calculate product
JOptionPane.showMessageDialog(null, "sum :"+sum+" "+ "difference :"+difference+" "+"product :"+product); // for displaying output.
}
private static double calculateSum(double value1, double value2) {
return value1+value2;
}
private static double calculateDifference(double value1, double value2) {
return value1-value2;
}
private static double calculateProduct(double value1, double value2) {
return value1*value2;
}
}
