我想给变量赋值并输出，请问怎么写
初学者不会
根据你的代码来看，如果你的类都放在同一个java文件中，那么首先得把test类定义为public。
比如
employee ，在 Test中
employee em=new employee (); //注意啊，类名按命名规范第一个字母要大写
介于你没有getter和setter
赋值只能这样 em.name="张三";
调用方法 em.say(); //继承于super
前面加上：import java.io.BufferedReader; import java.io.InputStreamReader;
public static void main(String [] arguments)throws Exception { System.out.println("请输入内容"); BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); String inputStr = br.readLine(); //readLine()；有按行读取的功能，你可以把上面的内容再重复一边，然后赋值到自己的变量里。 System.out.println(inputStr); } }
faculty f=new faculty();
f.say();
如果要输出：f.levent="值";
System.out.print(f.levent );
public class Person { String name; String address; String telphone; String email; public String getName() { return name; } public void setName(String name) { this.name = name; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } public String getTelphone() { return telphone; } public void setTelphone(String telphone) { this.telphone = telphone; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } void say(){ System.out.println ("person is saying"); } } class Employee extends Person{ String office; double wage; String hiredate;
public String getOffice() { return office; } public void setOffice(String office) { this.office = office; } public double getWage() { return wage; } public void setWage(double wage) { this.wage = wage; } public String getHiredate() { return hiredate; } public void setHiredate(String hiredate) { this.hiredate = hiredate; } } class Faculty extends Employee{ String degree; String level; public String getDegree() { return degree; } public void setDegree(String degree) { this.degree = degree; } public String getLevel() { return level; } public void setLevel(String level) { this.level = level; } public static void main(String[] args) { //实例化子类 Faculty f = new Faculty(); //给成员属性赋值 f.setAddress("中国"); f.setDegree("博士"); f.setEmail("123@163.com"); f.setHiredate("
在写出get set方法 以及输入的方法 或者直接给变量赋值 然后定义get方法 在main方法中用System.out.print();输出
