2,812 PointsNo need to import Character? Importing isn't better than just using?
1) The some previous class, I learned about import, import java.io.Console on the top in Prompter.java. But what I couldn't catch is... why do we need to import Console? I thinks there is some different point that I can't catch. "import java.io.Console" VS "import java.lang.Character"
2) <Prompter.java> : the practice code import java.io.Console; Console console = System.console();
With the practice code, I imagined like below.
<Game.java> import java.lang.Character; Character character = new Character();
or (just) Character character = new Character();
which one is correct?
3) if we import Character on the top in Game.java, we don't need to use "Character".isLetter We can just use isLetter.
Just want to know why he didn't import? Does it has any convention to import?
