Java中箭头键的Unicode是什么

Question

我正在尝试在Minecraft中编码Web浏览器，并且在箭头键上遇到了麻烦。什么是Unicode中的每个。我已经有了这个。是的，浏览器正在工作，我获得了鼠标输入以及完成的所有其他密钥。我包括type（）方法，key（）方法和getchar（）方法。它在获取字符中所做的一切并将其发送到type（）方法，以便Web浏览器知道如何输入它。

public void type(BlockSide side, String text, BlockPos soundPos) {

                            char chr = text.charAt(i);
