两个类，实例化问题，实例化报错

Question

public class Paixu {

public static void main(String[] args) {

    //   Paixu px=new Paixu();

    MaoPaoSort mp=new MaoPaoSort();

//上面这里就开始报错了：No enclosing instance of type Paixu is accessible. Must qualify the allocation with an enclosing instance of type Paixu (e.g. x.new A() where x is an instance of Paixu).
}

class MaoPaoSort {
    public  void test1() {
        int a[] = { 1, 1234, 356, 123, 56346, 73, 45342342, 1, 3, 56, };

        for (int i = 0; i < a.length; i++) {

            for (int j = i + 1; j < i - 1; j++) {
                if (a[i] < a[j]) {
                    int tmp = a[i];
                    a[i] = a[j];
                    a[j] = tmp;
                    System.out.println(a[j]);
                }
            }
        }

    }


}

}

不能在静态函数中new，把 MaoPaoSort改成静态的类
