java：student1异常

处理运行时异常的一种方法

public class Student1 {
    private int age;
    private String name;
    private String gender;

    public Student1() {
    }

    public Student1(int age, String name, String gender) {
        this.age = age;
        this.name = name;
       // this.gender = gender;
        this.setGender(gender);
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getGender() {
        return gender;
    }

    public void setGender(String gender) {
        if(gender.equals("男")||gender.equals("女")){
            this.gender = gender;
        }else {
            throw new RuntimeException();//我认为最简单的方法
        }

    }

    @Override
    public String toString() {
        return "Student1{" +
                "age=" + age +
                ", name='" + name + ''' +
                ", gender='" + gender + ''' +
                '}';
    }
}
//在同一个包下，不能有二个名字一样的类
class Test11{
    public static void main(String[] args) {
        Student1 s=new Student1(12,"lxl","男ii");
        System.out.println(s);

    }
}
