Constructor 建構子

Constructor 要取得跟該 class一樣的名字, 主要是在用 class 產生 object 時, initialize一些變數用

ex.

public class MyCat {
    private catName;

    public MyCat (String name) // constructor
    {
        catName = name;
    }

}

of course multiple inputs are acceptable


public class MyCat {
    private catName;
    int catAge;

    public MyCat (String name, int age) // constructor
    {
        catName = name;
        catAge = age;
    }

}
