`default DoublePredicate`	`negate()` 返回表示谓词逻辑否定的谓词。

DoublePredicate and (DoublePredicate other)

返回一个组合谓词，表示谓词与其他谓词的短路逻辑AND。在评估组合谓词时，如果此谓词为false ，则不评估other谓词。

Parameters
`other`	`DoublePredicate`: a predicate that will be logically-ANDed with this predicate

Returns
`DoublePredicate`	a composed predicate that represents the short-circuiting logical AND of this predicate and the `other` predicate

Throws
`NullPointerException`	if other is null
