构造方法调用另一个构造方法

一个构造方法可以调用其他构造方法，目的是为了方便代码复用。调用方法是this(…)

class Employee{
    private String name;
    private int salary;
    private String hireDay;

    public Employee(String name,int salary, String hireDay){
        this.name = name;
        this.salary = salary;
        this.hireDay = hireDay;
    }
    //一个构造方法可以调用其他构造方法，目的是为了方便代码复用。调用方法是this(...)
    public Employee(String name){
        // 传入参数name，salary,hireDay使用默认值
        this(name,40,"22"); //调用的是Employee(tring name,int salary, String hireDay)
    }
    public Employee(){
        //传入默认值参数name,调用的是Employee(String name)，所以name,salary,hireDay都是初始化的值
        this("abc"); // 调用的是Employee(String name)
    }

    public int getSalary() {
        return salary;
    }

    public String getName() {
        return name;
    }

    public String getHireDay() {
        return hireDay;
    }
    public void raiseSalary(double bypercent){
        int raise = (int) (salary * bypercent / 100);
        salary += raise;
    }
}
