I am having problems with fixing a source code for a calculator written in Java. The professor wants us to edit the CalculatorImpl.java file so that when run it adds, subtracts, multiplies and divides correctly. There is a Main class named Main that may be used to test your results. Do not modify Main. java, and CalculatorInterface. java files. Do keep a running total inside the calculator class. Can you assist me please?

 

NEEDS TO BE EDITED…(CalculatorImpl.java)publicclassCalculatorImplimplementsCalculatorInterface {privateinttotal;@Overridepublicvoidreset() {//TODOAuto-generated method stub}@Overridepublicdoubleplus(inta) {//TODOAuto-generated method stubreturn0;}@Overridepublicdoubleminus(inta) {//TODOAuto-generated method stubreturn0;}@Overridepublicdoubleslash(inta) {//TODOAuto-generated method stubreturn0;}@Overridepublicdoublestar(inta) {//TODOAuto-generated method stubreturn0;}@Overridepublicdoubleequal() {//TODOAuto-generated method stubreturn0;}}
