有时候，我们在书写代码的时候需要处理一些具有重复性的数据，比如，我要定义一个枚举，来源如下：
image.png
这时候一个个地敲就有些慢了。这时候就该祭出我们的Excel了。
首先，把内容复制后，贴入Excel
image.png
然后使用Data->Text To Columns，中文版的话是数据->分列，把它分割成单个元素。
image.png
这里我们选固定长度，因为当前这种情况用固定长度拆分更容易。

不过在许多其他的情况下，我们一般常用的是用各种分隔符来切分。
拆分好之后，调整一下。现在每列一种数据了，我们插入几列，并输入其他的内容，比如枚举的名称和括号：
image.png
然后，在最后一列，用函数 & 符号连接所有的元素。

最后，直接贴到代码中：
public enum PageSegmentMode {
OSD_ONLY(0),//Orientation and script detection (OSD) only.
AUTO_SEG_WITH_OSD(1),//Automatic page segmentation with OSD.
AUTO_SEG_NO_OSD(2),//Automatic page segmentation, but no OSD, or OCR.
FULLY_AUTO_NO_OSD(3),//Fully automatic page segmentation, but no OSD. (Default)
SINGLE_COLUMN_WITH_VARIABLE_SIZE(4),//Assume a single column of text of variable sizes.
SINGLE_BLOCK_WITH_VERTICAL_TXT(5),//Assume a single uniform block of vertically aligned text.
SINGLE_BLOCK_TXT(6),//Assume a single uniform block of text.
SINGLE_TXT_LINE(7),//Treat the image as a single text line.
SINGLE_WORD(8),//Treat the image as a single word.
SINGLE_WORD_IN_CIRCLE(9),//Treat the image as a single word in a circle.
SINGLE_CHAR(10),//Treat the image as a single character.
SPARSE_TXT_AS_MUCH_AS_POSSIBLE(11),//Sparse text. Find as much text as possible in no particular order.
SPARSE_TXT_WITH_OSD(12),//Sparse text with OSD.
RAW_LINE(13),//Raw line. Treat the image as a single text line, bypassing hacks that are Tesseract-specific.
private int value;
PageSegmentMode(int value) {
this.value = value;
}
}
或者，我们可以直接把JavaDoc也给它加上。单独选中每一行之后，点击插入，就会在每一行之前插入一行。然后把javadoc所需的内容放上去。

RAW_LINE (13)
之后整理一下格式，javadoc就好了。
