这个线程的循环为什么走不到里面?

我已经懂了,多谢大家哇!!!!!

public class Test4 {
    public static int j;
    public static void main(String[] args) {
        new Thread() {
            public void run() {
                int i=0;
                while(true) {
                    while(j>i) {
                        System.out.println(1111);
                    }
                }
            };
        }.start();
        try {
            Thread.sleep(5000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        j=1;
        System.out.println(j);
    }

}

public static int j;
默认，j = 0
修改为
public static int j = 1;
