unexpected output, confusion between float and integer

MEERA :

I have two statements in java:

System.out.println(2 * (5 / 2 + 5 / 2 ));

This generate the output 8 but again in next line:

System.out.println(2 * 5 / 2 + 2 * 5 / 2 );

This generate the output 10.

now my confusion is why it generates different output

please someone describe it. thanks

Andronicus :

Note, that division between ints generates an int (rounded down).

2 * (5 / 2 + 5 / 2) => 2 * (2 + 2) => 8

2 * 5 / 2 + 2 * 5 / 2 => 10 / 2 + 10 / 2 => 10

To get the exact value, you would have to use floats:

2 * (5.0 / 2 + 5.0 / 2) == 10
