Human有一个名为mName的String,它在构造函数中使用,而Bicycle有一个String mOwner,我需要将它们链接到另一个,我是新的(编程)所以我不确定我应该读什么更好理解。< / p>
我创建了findOwner方法,它返回mOwner,并声明了mName&#34; Dave&#34;在Human的构造函数中......我能以某种方式使findOwner方法返回当前Human对象的值吗?
抱歉我的英文,谢谢你)
这是我的代码:
public class Human {
public String mName;
public Human(String name){
mName = name;
}
}
/* this one is my Bicycle */
public class Hecaniv {
private String mOwner;
private int mSpeed;
private int mShift;
private int mWheels;
public Hecaniv(int shift, int speed, int wheels){
mSpeed = speed;
mShift = shift;
mWheels = wheels;
}
public int currentSpeed(){
return mSpeed;
}
public int currentShift(){
return mShift;
}
public int numOfWheels(){
return mWheels;
}
public String findOwner(){
return mOwner;
}
}
答案 0 :(得分:0)
您可以将所有者对象本身作为BlackPnL = np.zeros(10000000)
Black_S=np.random.randint(200, 10000, 10000000)*0.01
Black_Texpiry=np.random.randint(1,500,10000000)*0.01
Black_strike=np.random.randint(1,100,10000000)*0.1
Black_volatility=np.random.rand(10000000)*1.2
Black_IR=np.random.rand(10000000)*0.1
Black_callput=np.sign(np.random.randn(10000000))
Black_callput=Black_callput.astype(np.int64)
的字段,而不是拥有所有者的名称。
