确实，您可以使用Java语言来编写贪吃蛇游戏。下面是一个基本的示例：

```java

import java.awt.Color;

import java.awt.Dimension;

import java.awt.Font;

import java.awt.FontMetrics;

import java.awt.Graphics;

import java.awt.Image;

import java.awt.Toolkit;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import java.awt.event.KeyAdapter;

import java.awt.event.KeyEvent;

import javax.swing.ImageIcon;

import javax.swing.JPanel;

import javax.swing.Timer;

这是一个简单的贪吃蛇游戏示例，使用了Java Swing库来创建图形界面。您可以将上述代码保存为SnakeGame.java，并在其他类中实例化并运行该游戏。此示例还包括基本的碰撞检测、移动控制和游戏结束等功能。您可以根据需要扩展和修改代码，以使其符合您自己的需求和设计。
