public class Company { private String name; private String address; public String people; public String getName() {  return name; } public void setName(String name) {  this.name = name; } public String getAddress() {  return address; } public void setAddress(String address) {  this.address = address; }}

public class AttrTest { public static void main(String[] args) throws IllegalArgumentException, IllegalAccessException {  Company c=new Company();    c.setName("XX科技公司");    c.setAddress("地球村");    Field fields[]=c.getClass().getDeclaredFields();//获得对象所有属性  Field field=null;  String[]attr={"name","address"};  for (int i = 0; i < fields.length; i++) {   field=fields[i];   field.setAccessible(true);//修改访问权限   for (int j = 0; j < attr.length; j++) {    if (attr[j].equals(field.getName())) {     System.out.println(field.getName()+":"+field.get(c));//读取属性值    }   }  } }}
