java代码编程时，做初始化（不用new（）方法），怎么做？

Answer 1

 public class AccpTeacher {
    private String name;

    private int age;

    public AccpTeacher() {
        name = "无名氏";
        age = 22;
    }

    public AccpTeacher(String name) {
        this.name = name;
        this.age = 22;
    }

    public String toString() {
        return "名字是:" + name;
    }

    public String toString(int age, String name) {
        this.name = name;
        this.age = age;
        return "名字是:" + name + "；年龄是：" + age;
    }
}


public static void main(String[] args){
    // 实例化一个类
    Object accpTeacher = Class.forName(AccpTeacher.class.getName()).newInstance();
    System.out.println(accpTeacher);
}
