构造方法与面向对象
package demo3;
public class Student {
//成员变量
private String name;
private int age;
//构造方法
public Student(){
}
public Student(String name ,int age){
this.name=name;
this.age=age;
}
//成员方法
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public void show(){
System.out.println(" nihao");
}
}
2/ 新建一个输出类名
package demo3;
public class Test {
public static void main(String[] args) {
Student student = new Student();
student.show();
student.setName("dang");
System.out.println(student.getName());
}
}
