我有这个代码来检查字符串是否有 j 字符

import std.stdio;

void main() {
    const string name = "john";
    for (int i = 0;i < name.length;i++) {
        if (name[i] == "j") {
           writeln("the name variable contain character j");
        }
    }
}

然后我得到一个错误

import std.stdio;

void main() {
    const string name = "john";
    for (int i = 0;i < name.length;i++) {
        if (name[i] == "j") {
           writeln("the name variable contain character j");
        }
    }
}
