How to print both bool and double in same line?

Question

I am working on this very simple java problem which requires to print both the objects money and isTrue without skipping a line.

I have tried casting both objects to string but doesn't work. I know I could have two print statements but they would print on 2 differents lines. I need both to print as 9999.99false

class Main {
  public static void main(String[] args) {
    double money = 9999.99;
    boolean isTrue = false;
    System.out.println(money + isTrue);
  }
}

The output expected is 9999.99false

Thanks!

`System.out.println("" + money + isTrue);` but I would prefer `System.out.printf("%.2f%b%n", money, isTrue);` — Elliott Frisch, Sep 09 '19 at 01:33
Are you aware of `System.out.print`, which is like `println` but without starting a new line? — Dawood ibn Kareem, Sep 09 '19 at 01:34
If you used print twice instead of println, they'd be on the same line — OneCricketeer, Sep 09 '19 at 01:34

How are you learning Java? This should be covered in any basic tutorial. — WJS, Sep 09 '19 at 02:19

What is happening right now is the compiler is seeing that you are trying to add a double and a boolean together using the + operator, which it does not know how to do. One option is to use the below code:

System.out.println("" + money + isTrue);

The first String literal tells the compiler to add a String and a double, which the compiler can do successfully by implicitly converting the double to a String. The same thing happens with the boolean.

Since String is a class, and double and boolean are primitive types, casting does not work between the two like it would in C# (see here for more information on that).

This produces your expected output when run:

9999.99false
