标准类

所有的成员变量要使用private关键词修饰为每一个成员变量编写一对Getter/Setter方法编写一个无参数的构造方法编写一个全参数的构造方法

这样标准的类也叫 Java Bean

package Class; //code -> generate -> Getter and Setter //shortcut: Alt + insert public class Teacher { private int number; private String name; private char gender; public char getGender() { return gender; } public void setGender(char gender) { this.gender = gender; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getNumber() { return number; } public void setNumber(int number) { this.number = number; } }
