Java Question

I have created a simple program to test a few things.

Piece of the code:

`int n = 250 * (50 / 500) + 50;`

System.out.println(n);

I have expected the program to output

`75`

`50`

`50`

`75`

`75`

Any help is appreciated happily,

Thanks in advance.

Answer

Why does it output

`50`

instead of`75`

?

It's because 50 / 500 is 0.1, but since its integer division, it becomes 0 as the fractional part is cut off. It then multiplies 250 and 0, resulting in 0, then adding 50, thus yielding 50.

Are there any ways so that it outputs

`75`

?

```
int n = 250 * 50 / 500 + 50;
System.out.println(n);
```

The above will take 250 and multiply by 50 yielding 12500. Next it will do 12500 / 500, which results in 25. Lastly, it will add 25 and 50, resulting in 75.
