java short circuit operators -

my uncertainty precedence of short circuit operators.

classic illustration of short circuit operator below.

if(denom != 0 && num/denom > 10 )

here usage of shorthand operator allows prevent partition 0 error because num/denom never executed.

now question java says '/' operator has higher precedence '&&' , how come left side of '&&' evaluated before '/'.?

/ has higher precedence >, has higher precedence &&. so, expression

a && b / c > 0

is same as

a && (b / c) > 0

which same

a && ((b / c) > 0)

the look evaluated left right.

if a false, entire look false, without evaluating sec term.

if a true, b / c first evaluated, , result compared 0.
