Scala bitwise operation

Question

I am defining a simple function to do some bitwise operation :

def getBit(num:Int, i:Int):Boolean = (num & (1 << i) != 0)

But I am getting this error :

    <console>:7: error: overloaded method value & with alternatives:
  (x: Long)Long <and>
  (x: Int)Int <and>
  (x: Char)Int <and>
  (x: Short)Int <and>
  (x: Byte)Int
 cannot be applied to (Boolean)
       def getBit(num:Int, i:Int):Boolean = (num & (1 << i) != 0)

Why I cannot use the & operator ? How can I solve this error?

Answer 1

The following code should work: def getBit(num:Int, i:Int):Boolean = ((num & (1 << i)) != 0)
