定义一个Teacher类，该类有name、idg两个私有成员变量，通过构造方法将其进行赋初值，同时提供该成员的getXXX()和setXXX()方法，通过get方法取值。再写一个TestTeacher类，在类中创建一个教师对象并赋值，打印输出该教师对象信息。
提示：假设有private String name;则有 public void setName(String name){ this.name = name; } public String getName(){ return this.name; }
public class Teacher { private String name; private int idg; public Teacher(String name, int idg){ this.name = name; this.idg = idg; } public void setName(String name) { this.name = name; } public String getName() { return this.name; } public void setIdg(int idg){ this.idg = idg; } public int getIdg() { return this.idg; } } public class TextTeacher { public static void main(String[] args) { Teacher teacher=new Teacher("赵云",20); System.out.println(teacher.getName()); System.out.println(teacher.getIdg()); } }如果看不懂可以参照下篇getter方法和setter方法的详细介绍
