Thread: Conversion between primitive data types: mixed mathematical expressions

Hi everyone.

This is my first post. I read over the rules for posting and this section seemed like the best place to ask my question, however if it is not please direct me to the correct place!

A bit of back story so you understand why I'm asking such an odd question... I'm enrolled in the Computer Programmer Analyst program at my local college starting this fall and I've got a copy of the text book already so I am trying to read through it before classes begin. I'm brand new to the programming world so I know almost nothing.

I'm going to post a picture of the page so you can see exactly how the question is posed. I'm stuck on the Checkpoint question #26 because I'm not sure how I'm supposed to write out the statement.

I am fairly certain that I should be making variable "b" and "c" a float. But beyond that I'm confused.

Any advice is much appreciated! Thank you in advance and sorry for the long post for such a small question.

Ok..

The variable "a" is a FLOAT and the variable "b" is a DOUBLE. How can I write a statement that will assign the value of "b" to "a" without causing an error when the program is compiled?

My guess would be that it looks like this..

totalPay = float
basePay = 500
bonus = 1000

totalPay = (double) (basePay + bonus)

It's just giving me so many errors I don't even know where to start or how to explain.

This is what I have in eclipse...

package org.totalbeginner.tutorial;

public class person {
// practice

public class PayCheque
{
public static void main(String[] args)
{
// variables to calculate total pay from base and bonus

int totalPay = basePay + bonus;
basePay = 500, bonus = 1000

totalPay = float
totalPay = (double)(basePay + bonus)

Ok, I will. Thanks for the advice 😕
