Answer:
public class Calculator {
private int total;
private int value;
public Calculator(int startingValue){
// no need to create a new total variable here, we need to set to the our instance total variable
total = startingValue;
value = 0;
}
public int add(int value){
//same here, no need to create a new total variable. We need to add the value to the instance total variable
total = total + value;
return total;
}
/**
* Adds the instance variable value to the total
*/
public int add(){
// no need to create a new total variable. We need to add the value to the instance total variable
total += value;
return total;
}
public int multiple(int value){
// no need to create a new total variable. We need to multiply the instance total variable by value.
total *= value;
return total;
}
//We need to specify which value refers to which variable. Otherwise, there will be confusion. Since you declare the parameter as value, you need to put this keyword before the instance variable so that it will be distinguishable by the compiler.
public void setValue(int value){
this.value = value;
}
public int getValue(){
return value;
}
}
