我懂Java，然而我懵逼了= =

各位不怕死的，来猜一下输出顺序

public class MainClass {

	public static void main(String[] args) {
		staticFunection();
	}

	static MainClass st = new MainClass();

	static {
		System.out.println("1");
	}

	{
		System.out.println("2");
	}

	public MainClass() {
		System.out.println("3");
		System.out.println("a =" + a + ", b=" + b);
	}

	public static void staticFunection() {
		System.out.println("4");
	}

	int a = 110;
	static int b = 112;
}

2
3
a =110, b=0
1
4
