java基础总结——java面向对象——static——final——this

public class Helllo2
{

    final int a;

    public Helllo2(int a)
    {
        this.a = a;
    }

    final int b = 12;


    public void daying()
    {
        System.out.println("++++++++");
    }

    public void daying2()
    {
        this.daying();
        System.out.println("++++++++_________");
    }

    public static void main(String[] args)
    {
        Helllo2 as = new Helllo2(22);
        System.out.println(as.a);
        System.out.println(as.b);
        as.daying2();
