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.getN2());

printCircuit(a1);

}

}

1. Fill in all missing parts

2. Modify the main() method so that the output becomes:

Subtraction(2,3) = -1
