之前的文章《淺析EOS區塊鏈柚子錢包前端插件scatter開發(分享)》中,給大家了解了區塊鏈中EOS錢包前端插件scatter開發。以下這篇文章給大家了解java.util.function.*pojo反射新方法,夥伴們來看看一下。
上程式碼,看範例
#寫一個普通的POJO
public class City { private String name; private String code; public City() { } public City(String name, String code) { this.name = name; this.code = code; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getCode() { return code; } public void setCode(String code) { this.code = code; } }
傳統的方式
// Use a constructor with parameters to create a City City sf = new City("San Francisco", "SF"); // Use a default constructor with no parameters to create a City City la = new City(); // Set the members using setters la.setName("Los Angeles"); la.setCode("LA");
#新的getter存取方式##
// Use the City's method references and assign them to functions FunctiongetNameFunction = City::getName; Function getCodeFunction = City::getCode; System.out.println("The code for " + getNameFunction.apply(sf) + " is " + getCodeFunction.apply(sf)); -> The code for San Francisco is SF
新的setter存取方式
// Use the City's method references and assign them to biconsumers BiConsumersetNameBiConsumer = City::setName; BiConsumer setCodeBiConsumer = City::setCode; City ny = new City(); setNameBiConsumer.accept(ny, "New York"); setCodeBiConsumer.accept(ny, "NY");
#存取constructor 建立新實例
// Use the City's constructor method reference to create // a default constructor reference. SupplierdefaultConstructor = City::new; City sd = defaultConstructor.get(); sd.setName("San Diego"); sd.setCode("SD");
#帶有參數的建構器
// Use the City's constructor method reference to create // a two-parameter constructor reference. BiFunctiontwoParameterConstructor = City::new; City dc = twoParameterConstructor.apply("Washington, D. C.", "DC");
