public interface Supplier<T> { T get(); } Tis the type of results supplied by the supplier. Supplieroffers a concise and convenient way to represent value-providing functions, promoting lazy evaluation, code clarity, and compatibility with functional programming concepts in Java. Simple Supplier ex...

函数式接口:有且只有一个抽象方法的接口,称之为函数式接口当然接口中可以包含其他的方法(默认,静态,私有) @FunctionalInterface注解作用:可以检测接口是否是一个函数式接口 是:编译成功 否:编译失败(接口中没有抽象方法抽象方法的个数多余1个) 示例代码: @FunctionalInterface public interface MyFunctionalInterface { ...

Supplier在java的用法 supplier java Supplier是函数式编程的另一个接口,与Function、Predicate接口类似,区别在于Supplier不接收任何参数,只返回结果。 Supplier的基本使用 @FunctionalInterface public interface Supplier<T> { /** * Gets a result. * * @return a result...
package java.util.function; /** * Represents a supplier of results. * * There is no requirement that a new or distinct result be returned each * time the supplier is invoked. * * This is afunctional interface * whose functional method is {@link #get()}. ...
