difference between | and || operator

[Amisha Shah]

what is the difference between | and || operator?

[Keith Lynn]

The || operator when used between two boolean will use short-circuit evaluation. That is, if the truth of the entire statement can be determined by examining the first operand, then the other operand will not be evaluated. Using the | operator both will be evaluated.

[Prad Schikanov]

What's more | is a bitwise operator too, where as || is just a boolean operator.

10 | 5
//will give you 15


true | false
//will give you true,
//both the operands will be evaluated,
//even though first operand is already true.


10 || 15
//a nice compiler error!


true || false
//as the first operand is true,
//second operand will not be evaluated

Regards,
Priyanka.
