Jan 2, 2024 · Video Call (Android Java) Application Scenarios The SDK mainly uses the bitmask principle to implement multiple switch operations, that is, when multiple module switches need to be selected in an API, developers need to pass the bitmask result to the SDK.

(10 answers) Bit wise shift operator with shift by negative number (1 answer) Java adds the operator ">>> " to perform logical right shifts, but since the logical and arithmetic left-shift operations are identical for signed integer, there is no " <<<" operator in Java. Thus when we cast back to a short in our example all bits shifted in after our signed bit are 1 and we get an unexpected result.
