编写一个自行车类，包含：品牌，价格，型号等属性，包含显示属性的方法，及构造方法。

要求在测试类中实例化自行车类，并进行实例化对象数量的统计

自行车类

public class Bycircle {

    private String mBrand;
    private int mPrice;
    private String mXh;
    public static int count = 0; 
    public Bycircle(String b,int p,String xh){
        mBrand = b;
        mPrice = p;
        mXh = xh;
        count++;
    }
    @Override
    public String toString() {
        return "Bycircle [mBrand=" + mBrand + ", mPrice=" + mPrice + ", mXh=" + mXh + "]";
    }
    public String getmBrand() {
        return mBrand;
    }
    public void setmBrand(String mBrand) {
        this.mBrand = mBrand;
    }
    public int getmPrice() {
        return mPrice;
    }
    public void setmPrice(int mPrice) {
        this.mPrice = mPrice;
    }
    public String getmXh() {
        return mXh;
    }
    public void setmXh(String mXh) {
        this.mXh = mXh;
    }
}

测试类：

import java.util.Scanner;

public class Test2 {
    
    public static void main(String[] args) {
        Bycircle b1 = new Bycircle("小刀",2000,"xx1");
        Bycircle b2 = new Bycircle("小刀",2001,"xx2");
        System.out.println(b1);
        System.out.println(b2);
        System.out.println("数量："+b2.count);
        
    }

}
