之前的文章《浅析EOS区块链柚子钱包前端插件scatter开发（分享）》中，给大家了解了区块链中EOS钱包前端插件scatter开发。下面本篇文章给大家了解java.util.function.*pojo反射新方法，伙伴们来看看一下。
上代码，看例子
写一个普通的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;
}
}传统的方式
// 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访问方式
// 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
新的setter访问方式
// 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");
访问 constructor 创建新实例
// 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");
带参数的构建器
// 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");
