/** * 业务流程模板,提供基本框架 * @author stone * */ public abstract class BaseTemplate { public abstract void part1(); public abstract void part2(); public abstract void part3(); //这里为了严格实验结果,使用final不可被重写 public final void useTemplateMethod() { part1(); part2(); part3(); } }

/** * 模板方法(TemplateMethod)模式:行为型模式,定义了一系列操作的骨架,将模块的实现 延迟到实现类或者子类中实现。 * 跟建造者模式的区别: * 建造者模式,使用组合方式,由指挥者Director指挥组合的Builder建造,建造流程由Director控制,建造的模块方法由Builder实现 * 模板方法模式,由模板定义操作流程,由子类或实现类 实现具体的模块方法 * 综上,建造者模式灵活于模板方法模式 * @author stone * */ public class Test { public static void main(String[] args) { BaseTemplate tm = new TemplateMethod(); tm.useTemplateMethod(); System.out.println(""); BaseTemplate tm2 = new TemplateMethod2(); tm2.useTemplateMethod(); } }

Java 8 introduces the Stream API, providing a powerful and expressive way to process data collections. However, a common question when using Stream is: How to break or return from a forEach operation? Traditional loops allow for early interruption or return, but Stream's forEach method does not directly support this method. This article will explain the reasons and explore alternative methods for implementing premature termination in Stream processing systems. Further reading: Java Stream API improvements Understand Stream forEach The forEach method is a terminal operation that performs one operation on each element in the Stream. Its design intention is

Capsules are three-dimensional geometric figures, composed of a cylinder and a hemisphere at both ends. The volume of the capsule can be calculated by adding the volume of the cylinder and the volume of the hemisphere at both ends. This tutorial will discuss how to calculate the volume of a given capsule in Java using different methods. Capsule volume formula The formula for capsule volume is as follows: Capsule volume = Cylindrical volume Volume Two hemisphere volume in, r: The radius of the hemisphere. h: The height of the cylinder (excluding the hemisphere). Example 1 enter Radius = 5 units Height = 10 units Output Volume = 1570.8 cubic units explain Calculate volume using formula: Volume = π × r2 × h (4
