I'm essentially asking the same as this old question, but for Java 14 instead of Java 8. To spare answerers the trouble of navigating to the old question, I'll rephrase it here. I want to get the name of a function from a referenced method. The following Java code should give you the idea:
public class Main
{
public static void main(String[] args)
{
printMethodName(Main::main);
}
private static void printMethodName(Consumer<String[]> theFunc)
{
String funcName = // somehow get name from theFunc
System.out.println(funcName)
}
}
The equivalent in C# would be:
public class Main
{
public static void Main()
{
var method = Main.Main;
PrintMethodName(method)
}
private static void PrintMethodName(Action action)
{
Console.WriteLine(action.GetMethodInfo().Name);
}
}
According to the accepted answer of the old question, this was not possible in Java 8 without considerable work, such as this solution. Is there a more elegant solution in Java 14?
