javapackage java.util.function;
/** * 表示结果提供者。 * 无需每次调用提供者时都返回新的或不同的结果。 */
Supplier接口
package java.util.function; /** * Represents a supplier of results. * * <p>There is no requirement that a new or distinct result be returned each * time the supplier is invoked. * * <p>This is a <a href="package-summary.html" rel="external nofollow" rel="external nofollow" >functional interface</a> * whose functional method is {@link #get()}. * * @param <T> the type of results supplied by this supplier * * @since 1.8 */ @FunctionalInterface public interface Supplier<T> { /** * Gets a result. * * @return a result */ T get(); }
supplier接口只有一个抽象方法get(),通过get方法产生一个T类型实例。
