Vector.isUnsigned介绍

[英]Returns true if integer values shall be interpreted as unsigned values. This method may return true for data stored in byte[], short[], int[]or long[] arrays, but never for data stored in float[] and double[] arrays.

Unless otherwise noticed in Javadoc, users do not need to care about this information since Vector methods will perform automatically the operations needed for unsigned integers.
[中]如果整数值应解释为无符号值，则返回true。对于字节[]、短[]、int[]或长[]数组中存储的数据，此方法可能会返回true，但对于浮点[]和双[]数组中存储的数据，则不会返回true。
除非Javadoc中另有说明，否则用户不需要关心这些信息，因为向量方法将自动执行无符号整数所需的操作。
