是否可以在类定义中创建类的对象,而无需使用默认构造函数

public class OuterClass {
    private int x;

    public OuterClass(int x) {
        this.x = x;
    }

    public class InnerClass {
        private int y;

        public InnerClass(int y) {
            this.y = y;
        }

        public void print() {
            System.out.println("x = " + x + ", y = " + y);
        }
    }

    public static void main(String[] args) {
        OuterClass outer = new OuterClass(10);
        OuterClass.InnerClass inner = outer.new InnerClass(20);
        inner.print();
    }
}
