解释型或即时编译型的编程语言。虽然它是作为开发Web页面的脚本语

JavaScript（简称“JS”） 是一种具有函数优先的轻量级，解释型或即时编译型的编程语言。虽然它是作为开发Web页面的脚本语言而出名，但是它也被用到了很多非浏览器环境中，JavaScript 基于原型编程、多范式的动态脚本语言，并且支持面向对象、命令式和声明式（如函数式编程）风格。[1]

public class Employee extends Human {

    private String  workNo;

    private String salary;

    private int count;

    public Employee(String idCard, String name, String sex, int age, String workNo, String salary, int count) {
        super(idCard, name, sex, age);
        this.workNo = workNo;
        this.salary = salary;
        this.count = count;
    }

    public Employee() {
    }

    public String getWorkNo() {
        return workNo;
    }

    public void setWorkNo(String workNo) {
        this.workNo = workNo;
    }

    public String getSalary() {
        return salary;
    }

    public void setSalary(String salary) {
        this.salary = salary;
    }

    public int getCount() {
        return count;
    }

    public void setCount(int count) {
        this.count = count;
    }

    @Override
    public String toString() {
        return "Employee{" +
                "workNo='" + workNo + '\'' +
                ", salary='" + salary + '\'' +
                ", count=" + count +
                '}';
    }
}

public class TestClass {

    public static void main(String[] args) {
        Employee e1 = new Employee("123","aa","男",11,"01","1000",11);
        Employee e2 = new Employee("124","bb","男",12,"A1","2000",16);
        System.out.println(e1);
        System.out.println(e2);

        if(e1.getAge() > e2.getAge()) {
            System.out.println(e1);
        }else {
            System.out.println(e2);
        }

        System.gc();
        System.out.println(e1);
        System.out.println(e2);
    }
}

具体的方法有些多，需要慢慢写，请稍等
