java 类静态成员初始化问题

public class StaticVar {
	private static StaticVar sv = new StaticVar();
	public  static int i;
	public  static int j = 0;

	private StaticVar() {
		i ++;
		j ++;
	}
	
	public static StaticVar getInstance(){
		return sv;
	}

	public static void main(String[] args) {
		//StaticVar sv = StaticVar.getInstance();	
		System.out.println("i = " + i);
		System.out.println("j = " + j);
	}
}

使用javap -v 反编译后关于静态区的内容

static {};
  Code:
   Stack=2, Locals=0, Args_size=0
   0: new #14; //class StaticVar
   3: dup
   4: invokespecial #15; //Method "<init>":()V
   7: putstatic #4; //Field sv:LStaticVar;
   10: iconst_0
   11: putstatic #3; //Field j:I
   14: return
  LineNumberTable:
   line 2: 0
   line 4: 10
