java為什么可以不寫類名直接調(diào)用返回類的靜態(tài)方法嘛？?public?R?getVerifyCode(@RequestParam("phoneNumber")?String?phoneNumber)?{
????????if?(!isPhoneNumber(phoneNumber))?return?error("Is?not?a?valid?phone?number");
????????}public?class?R<T>?{、
public?static?R?error()?{
????????return?new?R(ERROR,?"error",?"");
????}
}
直接調(diào)用返回類的靜態(tài)方法的解釋
