java中getName()、getCanonicalName()、getSimpleName()用法比较

package com.reflect;

public class User {
    private String name;
    private String password;
    private int age;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }
}

package com.reflect;

public class ReflectDemo {
    public static void main(String[] args) {
        User u=new User();
        print(u.getClass().getName());
        print(u.getClass().getCanonicalName());
        print(u.getClass().getSimpleName());
        print(args.getClass().getName());
        print(args.getClass().getCanonicalName());
        print(args.getClass().getSimpleName());
    }

    public static void print(Object o) {
        System.out.println(o.toString());
    }
}
