给段最简单的java代码 让我新手看一下

最简单的java代码肯定就是这个了，如下：

public class MyFirstApp

{

public static void main(String[] args)

{

System.out.print("Hello world");

}

}

“hello world”就是应该是所有学java的新手看的第一个代码了。如果是零基础的新手朋友们可以来我们的java实验班试听，有免费的试听课程帮助学习java必备基础知识，有助教老师为零基础的人提供个人学习方案，学习完成后有考评团进行专业测试，帮助测评学员是否适合继续学习java，15天内免费帮助来报名体验实验班的新手快速入门java，更好的学习java！

求用java编出一个船的形状，要用小星星为轮廓，我画的不好，求个java语句

private static final String NEWLINE = System.getProperty("line.separator");

String dots =

" "+".::::. " + NEWLINE +

" " +" " +" .:::::" +":::. " +

NEWLINE + " ::::::::::: " + NEWLINE +

" " + " ':::::::::::.. "

+ NEWLINE +" ::::" +":::::::::::' " + NEWLINE +" ':::::::::::. " + NEWLINE +

" .::::::::" +"::::::' " + NEWLINE +" " +".:::::::::::... " + NEWLINE +

" ::::::::::::::''" +

" " + NEWLINE +" .:::. '::::::::'':::: " + NEWLINE +

" .::::::::. " +

" ':::::' ':::: " + NEWLINE +" "

+".::::':::::::. " +" ::::: '::::. " + NEWLINE +" .:::::' '::::"

+"::::::: :::... " + NEWLINE +" ..:::: ':::::::::' " +

" .:' '''' " + NEWLINE +" ..''''':' ':::::.' " + NEWLINE;

System.out.println(dots);

第1步：

2鬼上船 2鬼 过河 1鬼上岸; 1鬼 回来

第2步：

1鬼上船 2鬼 过河 1鬼上岸; 1鬼 回来 1鬼上岸

第3步：

2人上船 2人 过河 1人上岸; 1鬼上船 1人1鬼 回来 1鬼上岸

第4步：

1人上船 2人 过河 2人上岸; 1鬼上船 1鬼 回来

第5步：

1鬼上船 2鬼 过河 1鬼上岸; 1鬼 回来

第6步：

1鬼上船 2鬼 过河 2鬼上岸; 回来

成功过河小船的Java代码了！

我的世界船怎么做？

参考下面方法制作：

操作工具：安卓手机

1、船需要用到木头，先去找到树木获得木块。

2、然后用木块合成木板，一个木块可以合成四个木板。

3、接着先用木板合成工作台，然后将合好的工作台放在地上。

4、然后在工作台这里，右击工作台，用五块木板合成小船。

5、最后就完成船的制作了，接下来我们将小船放在水里。

6、右击小船即可乘坐到船上，按方向即可前进。
