利用封装的思想，描述人类这个抽象的类。（属性方法自拟）

package kaoshi;

public class two {
public static void main(String[] args) {
Person xm=new Person("小明",20);
xm.jieshao();
}
}
class Person{
private String name;
private int age; 简单source CF
public Person(String name, int age) {
super();
this.name = name;
this.age = age;
} 简单source CS
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public void jieshao(){ 简单syso alt+？ 直接出
System.out.println("我是"+this.name+",我"+this.age+"岁了");
