这个工具类是否有2个静态方法线程安全？(Is this utility class with 2 static methods threadsafe?)

 以下Utility类在其内部调用相同的静态方法，但没有共享的全局变量。 但它看起来像nameTo（）方法是“共享”和一个问题。 我是否正确，并且它不安全？ 
 
public class Utility 
{
    public static MyObject create_1(boolean b)
    {
        MyObject o = new MyObject();
        o.setName(nameTo(b));           
        return o;
    }

    public static MyObject create_2(boolean b)
    {
        MyObject o = new MyObject();
        o.setName(nameTo(b));           
        return o;
    }

    public static String nameTo(boolean b)
    {
        if(b)
            return "NameA";
        else
            return "NameB";         
    }
}

The following Utility class calls within itself the same static methods, but has no shared global variables. But it looks like the method nameTo() is "shared" and an issue. Am I right with it, and that it's unsafe?
 
public class Utility 
{
    public static MyObject create_1(boolean b)
    {
        MyObject o = new MyObject();
        o.setName(nameTo(b));           
        return o;
    }

    public static MyObject create_2(boolean b)
    {
        MyObject o = new MyObject();
        o.setName(nameTo(b));           
        return o;
    }

    public static String nameTo(boolean b)
    {
        if(b)
            return "NameA";
        else
            return "NameB";         
    }
}
