When I use System.out.print() the console doesn’t show anything, it only works if I put System.out.println() . Is there something I’m doing wrong?

```
import java.util.Scanner;

public class Calculator {
    
    public static void main(String[] args) {
    
        Scanner scanner = new Scanner(System.in);

        System.out.print("Principal : ");
        int principal = scanner.nextInt();
       
        System.out.print("Annual Interest Rate: ");
        float aInterestR = scanner.nextFloat();
        
        System.out.print("Period (Years): ");
        byte period = scanner.nextByte();
        
        double mortgage = principal * ((aInterestR*(1+aInterestR) * period)/(1+aInterestR)* period-1);
        

    
    
    }
    
    
    
}
```

The program worked well on my machine. However, in your code, the final mortgate didn’t show. You should print it.

And a quick reminder, you should use an “int” or “long” to store any non-technical integer value and “double” for any non-technical decimal value, even it is far less likely to exceed the limit. Bytes, Shorts, Floats are built for talking to your hardware.

Hi,  
Yes you didn’t calculate the **period** and your mortgage formula is not correct.  
Watch the solution or download the source file to see the code mosh used to calculate the mortgage

That looks like a glitch that I had with IntelliJ  
Are you using IntelliJ?  
Have you restarted the program?

When I had this issue, it would not use print(), but would use println().  
It also wouldn’t print Strings \> it would only print the reference to the memory.  
Mine required a restart and resolved both issues.
