System.out.printf("nLemieux's number is even: %s ", predicateExample.test(66)); } } Java Predicate lambda 示例 当然,如果您正在学习Java 8的Predicate接口,您很可能对如何在Lambda函数中使用它感兴趣。 Lambda表达式的目标是减少Java代码的冗长性,特别是在需要覆盖只有一个功能方法的接口的情况下。以下是...
Predicate<Employee> isMinor = isAdult.negate(); 3. Using Predicate with Java 8 Stream As we know, the Predicate is a functional interface, meaning we can pass it in lambda expressions wherever a predicate is expected. For example, one such method is filter() method from the Stream interfac...
