Java程序自定义异常程序编写

Question

编写应用程序，名称为负工资异常（当工人的工资为负数时产生该异常）。创建两个工人对象，分别应用该异常。注:验证用户自定义异常

Answer 1

public class MyException extends Exception{ //创建自定义异常
    public MyException(String ErrorExceptin){ //构造方法
        super(ErrorExceptin);
    }
}

public class Employee {
    private String name;
    private int salary;
    public Employee(String name, int salary) throws MyException {
        if (salary<0){
            throw new MyException("工资不能为负数！！！");
        }
        this.name = name;
        this.salary = salary;
    }
    public int getSalary() {
        return salary;
    }
    public void setSalary(int salary) throws MyException {
        if (salary<0){
            throw new MyException("工资不能为负数！！！");
        }
        this.salary = salary;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public static void main(String[] args) throws MyException{
        Employee e1=new Employee("小白",-100);
        Employee e2=new Employee("小黑",20);
    }
}
