理解java8中java.util.function.*pojo反射新方法（附程式碼）

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; } }

// 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");

// Use the City's method references and assign them to functions Function getNameFunction = 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

// Use the City's method references and assign them to biconsumers BiConsumer setNameBiConsumer = City::setName; BiConsumer setCodeBiConsumer = City::setCode; City ny = new City(); setNameBiConsumer.accept(ny, "New York"); setCodeBiConsumer.accept(ny, "NY");

// Use the City's constructor method reference to create // a default constructor reference. Supplier defaultConstructor = City::new; City sd = defaultConstructor.get(); sd.setName("San Diego"); sd.setCode("SD");

// Use the City's constructor method reference to create // a two-parameter constructor reference. BiFunction twoParameterConstructor = City::new; City dc = twoParameterConstructor.apply("Washington, D. C.", "DC");
