简述Paragraph与Hadoop的区别
时间: 2023-10-07 07:07:25 浏览: 36
Paragraph和Hadoop是两个完全不同的技术。
Paragraph是一种文本排版工具,用于将文本内容排版为可读性更高的格式,如将短句子分段、添加标题、引用等。Paragraph通常用于写作、编辑和排版文档。
Hadoop是一种分布式计算技术,用于处理大规模数据集。Hadoop可以将大数据集切分成多个小数据块,并在多台计算机上并行处理这些数据块,从而实现高效的数据处理和分析。Hadoop主要用于大数据处理、数据挖掘、机器学习等领域。
因此,Paragraph和Hadoop是两种不同的技术,用于不同的领域。Paragraph主要用于文本排版,Hadoop主要用于大数据处理。

paragraph setalignment
`setAlignment()`是一个用于设置段落对齐方式的方法。它可以用于控制文本在段落中的位置。在使用该方法时,可以传入参数来指定段落的对齐方式,如左对齐、右对齐、居中对齐或两端对齐等。例如,以下代码将一个段落设置为居中对齐:
```
Paragraph paragraph = new Paragraph("This is a centered paragraph.");
paragraph.setAlignment(TextAlignment.CENTER);
```
这将使该段落中的文本在页面中居中对齐。可以使用相同的方法设置其他对齐方式。
itextpdf paragraph
iText is a popular open-source PDF library for Java that allows developers to create, manipulate, and extract data from PDF documents. To create a paragraph in iText, you can use the Paragraph class, which is part of the com.itextpdf.text package. Here is an example code:
```
Document document = new Document();
PdfWriter.getInstance(document, new FileOutputStream("example.pdf"));
document.open();
Paragraph paragraph = new Paragraph("This is a paragraph.");
document.add(paragraph);
document.close();
```
In this example, we create a new document, add a paragraph to it, and then close the document. The Paragraph constructor takes a String as its argument, which is the text that will be displayed in the paragraph. You can also customize the appearance of the paragraph by setting properties such as font, alignment, and spacing.
