Create an application named SalesTransactionDemo that declares several SalesTransaction objects and displays their values and their sum. The SalesTransaction class contains fields for a salesperson name, sales amount, and commission and a readonly field that stores the commission rate. Include three constructors for the class. One constructor accepts values for the name, sales amount, and rate, and when the sales value is set, the constructor computes the commission as sales value times the commission rate. The second constructor accepts a name and sales amount, but sets the commission rate to 0. The third constructor accepts a name and sets all the other fields to 0. An overloaded + operator adds the sales values for two SalesTransaction objects.

Answer:

Explanation:

The following code is all written in Java, first I will add the object initialization and declaration code that can be added to the main method of any program. Then I have also written the entire SalesTransaction class as the question was not clear as to exactly which was needed.

//Object Creation to copy and paste into main method

SalesTransaction sale1 = new SalesTransaction("Gabriel", 25, 5);

SalesTransaction sale2 = new SalesTransaction("Daniela", 5);

SalesTransaction sale3 = new SalesTransaction("Jorge");

//SalesTransaction class with three constructors

package sample;

class SalesTransaction {

   String name;

   int salesAmount, commission;

   private int commissionRate;

   public SalesTransaction(String name, int salesAmount, int rate) {

       this.name = name;

       this.salesAmount = salesAmount;

       this.commissionRate = rate;

       commission = salesAmount * rate;

   }

   public SalesTransaction(String name, int salesAmount) {

       this.name = name;

       this.salesAmount = salesAmount;

       this.commissionRate = 0;

   }

   public SalesTransaction(String name) {

       this.name = name;

       this.salesAmount = 0;

       this.commissionRate = 0;

   }

}
