# operator & abstract method

- int other

Bit-wise and operator.

Treating both `this`

and `other`

as sufficiently large two's component
integers, the result is a number with only the bits set that are set in
both `this`

and `other`

If both operands are negative, the result is negative, otherwise the result is non-negative.

```
print((2 & 1).toRadixString(2)); // 0010 & 0001 -> 0000
print((3 & 1).toRadixString(2)); // 0011 & 0001 -> 0001
print((10 & 2).toRadixString(2)); // 1010 & 0010 -> 0010
```

## Implementation

`int operator &(int other);`
