Bearing property has input range for angle, but not for degrees.

The direction API accepts a list of tuples for the angle from true north, and degrees that we can deviate.

Directions API will accept 0-360 for the angle (including -0 interestingly enough) but will error outside of that range.

Directions API will accept 0-180 for the degrees and will error outside of that range.

In the inline documentation for Bearing we mention this 0-360 range of accepted values for angle but omit the 0-180 for degrees. We should update the 0-180 documentation so developers will see this in their IDE (and know not to pass degrees beyond 180).

首先，在 Java SDK 中定位 Bearing 属性及其内联文档。更新 degrees 的描述，说明接受的值范围为 0-180，然后验证文档是否明确将其与 0-360 的角度范围区分开来，并且是否正确显示在 IDE 文档中。
