小编Ali*_*san的帖子

当我编写代码时，我在代码的第 10 行收到警告。谁能告诉我这个警告是什么意思？

我的代码

// SPDX-License-Identifier: UNLICENSED

pragma solidity >=0.5.0 < 0.9.0;

contract PracticeTest // It's a class
{
    string name ;
    uint256 age;

    constructor() public
    {
        name = "Ali";
        age = 21 ;
    }
}

这是警告

Warning: Visibility for constructor is ignored. If you want the contract to be non-deployable, making it "abstract" is sufficient.
