无参构造方法与多参构造方法练习

public class TestTeacher{ public static void main(String[] args){ Teacher t1 = new Teacher(); t1.name = ""; t1.sex = ""; t1.salary = 1.1; } } class Teacher{ String name; String sex; double salary; //无参构造方法 public Teacher(){ System.out.println("Teacher()....Executed"); } //一参构造方法 构造对象 public Teacher(String name){ System.out.println("Teacher(String)....Executed"); } //两参构造方法 public Teacher(String name,int age){ System.out.println("Teacher(String,int)....Executed"); } }
