64位Java未正确安装[关闭](64 bit Java is not installing properly [closed])

现在我不是一个非常有经验的程序员或计算机人员,如果这是专家在这里遇到的重复问题,那就很抱歉。

所以我有一个Bukkit Minecraft服务器,我希望扩展,这是我用来运行服务器的代码:(在.bat中)

java -Xmx1.5G -jar bukkit.jar

据我所知,-Xmx1.5G是我的服务器允许使用的最大内存量。 当我把它扩展到2G时,它告诉我我无法分配足够的空间,或者用一些类似的措辞。 我做了一些轻微的研究,我发现32位Java安装可以处理的数量有一些限制。

所以,我卸载了32位版本的Java,并重新安装了64位版本。 (我知道我使用的是64位计算机)当我转到Program Files(x86)时,我没有看到Java文件夹。 现在我也看到错误'java不被识别为内部或外部命令'。 我尝试将Java添加到我的系统路径,但没有运气。

谢谢。


Now I am not a very experienced programmer or computer person, so sorry if this is a repetitive problem that experts encounter here.

So I have a Bukkit Minecraft server that I am wishing to expand, here is the code that I am using to run the server: (In a .bat)

java -Xmx1.5G -jar bukkit.jar

From what I can tell, the -Xmx1.5G is is the maximum amount of memory that my server is allowed to use. When I expanded it to 2 G, it told me I could not allocate enough space, or in some similar wording. I did some light research and I discovered that there was some sort of limit on the amount a 32 bit Java installation could handle.

So, I uninstalled the 32 bit version of Java, and I re-installed the 64bit version. (I know that I am using a 64 bit computer) When I go to Program Files (x86), though, I do not see a Java folder. Now also I am seeing the error 'java is not recognized as an internal or external command'. I tried adding Java to my system path, and no luck.

Thanks.

部分是括号是有意义的。

let g = (5)

...意味着g是一个由一个Int组成的元组 ,符号化(Int) 。 它是(5,6)的单元素版本,符号化(Int,Int)

一般来说,你需要非常小心Swift中的括号; 他们不能只用于任何旧地方。 它们有意义。

但是,部分代码完成机制也是错误的。 如果您有可重复使用的情况,请向Apple提交报告。


Partly it's that parentheses are meaningful.

let g = (5)

...means that g is to be a tuple consisting of one Int, symbolized (Int). It's a one-element version of (5,6), symbolized (Int,Int).

In general you need to be quite careful about parentheses in Swift; they can't just be used any old place. They have meaning.

However, it's also partly that the code completion mechanism is buggy. If you have a reproducible case, file a report with Apple.
