编写JAVA程序实现如下功能：声明并定义Teacher类，（属性：教师编号、姓名和编号，输出教师的这些信息）；生成Teacher类的两个对象，输出对象的基本信息。

public class teacher                        //声明教师类
{
    public String id;                       //成员变量
    public String  name;
    public String specialty;
    public teacher(String id, String name, String specialty){
        this.id = id;
        this.name = name;
        this.specialty = specialty;
    }
    public void showset(){
        System.out.println("教师编号"+id  +",  姓名"+name+    ",  专业"+specialty);
    }

    public static void main(String[] args) {
        teacher t1=new teacher("1","张三","计算机");//声明对象并赋值
        teacher t2=new teacher("111","李四","材料");
        t1.showset();//调用成员方法
        t2.showset();
    }


}
