Answer:
Using names in formulas makes it clearer to see what the function is.
Explanation:
Just answered this in my online course.
Answer:
public class Calculator {
public double add(int a, int b){
return a+b;
}
public double substract(int a, int b){
return a-b;
}
public double multiply(int a, int b){
return a*b;
}
public double divide(int a, int b){
if(b>0){
return a/b;
}
else{
System.out.println("Cannot divide by zero");
}
return -1;
}
}
Explanation:
- Using Java Programming Language, the class Calculator is created. There are no fields (Instance variables) and no constructors since these are not required by the question.
- Four methods (functions) are created: add, substract, multiply and divide as specified in the question.
- Note the use of the if statement in the divide() to handle case of illegal division (by 0)
