标准的javaBean

package cn.bdqn.test;

public class javaBean {
    
    private  String name;
    private int age;
    
    public javaBean(){
        
    }
    public javaBean(String name,int age){
        this.name=name;
        this.age=age;
    }

    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;
    }

    @Override
    public String toString() {//toString可以使用快捷键生成
        return "javaBean{" +
                "name='" + name + '\'' +
                ", age=" + age +
                '}';
    }
}
