difference between (double)(1/2) and (double)1/2 in java [duplicate]

This question already has an answer here:

• What is the priority of casting in java? 1 answer

I want to know the difference between

System.out.print((double)1/2);
System.out.print((double)(1/2));

The first answer I got was 0.5, but the second one gives 0.0 . Thanks in advance.
