給float參數或Double型參數賦值為0 ，但初始化仍然是0.0；我想問一下，如何讓參數初始化為0 呢？private float oneNumber = 0 ;private Double twoNumber = 0.0 ;public float getOneNumber() { return oneNumber;}public void setOneNumber(float oneNumber) { this.oneNumber = oneNumber;}public Double getTwoNumber() { return twoNumber;}public void setTwoNumber(Double twoNumber) { this.twoNumber = twoNumber;}他們的get方法返回0.0，我怎么可以讓它等于0.0時，賦值為0？？
