Why no error on dividing by zero

Processing Beginners

Namaste everyone,

Why does “int x = 200/0;”
gives an error but

int x = 200/20*0; gives the value as 0.?

Thanks.

Because 200/20*0 is (200/20)*0, not 200/(20*0).

Hello @prathmesh,

A search for:

operator precedence Java

will reveal the answer to your question.

The Oracle Java documentation:
https://docs.oracle.com/javase/tutorial/java/nutsandbolts/operators.html

Parentheses discussed here:

When writing compound expressions, be explicit and indicate with parentheses which operators should be evaluated first. This practice makes code easier to read and to maintain.
