When running javaapplication8, the following output is seen on the display: addition(2,3) = 5 javaapplication. java is given below with some missing parts in the circuit class and printcircuit method (missing parts are identified by dots): class circuit{ private string operation; private int number1, number2, output; public circuit(int n1, int n2){ …} public void setnumbers(int n1, int n2){ …} public void setoperation(…){operation=op; } public void setn1(int n){number1 = n; } public void setn2(int n){number2 = n; } public void setoutput(int n){… = n; } public … getoperation(){return operation; } public … getn1(){return number1; } public int getn2(){…} public int getoutput(){return output; } } public class javaapplication8 { private static void printcircuit(circuit a) { … } public static void main(string[] args) { circuit a1 = new circuit(2,3); a1.setoperation("addition"); a1.setoutput(a1.getn1()+a1.; printcircuit(a1); } } 1. fill in all missing parts 2. modify the main() method so that the output becomes: subtraction(2,3) = -1
