How does the office software in Kirin OS meet your work needs?

With the continuous development of information technology, office software has become one of the necessary tools in the modern workplace. Among many operating systems, Kirin operating system is highly regarded for its stability, reliability, security and efficiency. This article will explore how the office software in Kirin operating system meets our work needs, and explain in detail with code examples.

Kirin operating system provides a series of excellent office software, such as document editor Writer, spreadsheet software Calc, and slideshow production software Impress. We can use these software to complete daily word processing, data analysis and presentation work.

First of all, let us take Writer as an example to introduce how the office software in Kirin operating system meets our word processing needs.

Writer is a powerful word processing software in Kirin operating system, with complete functions and easy operation. We can use Writer to create and edit various types of documents, such as reports, letters, papers, etc.

For example, when we need to write a report, we can open the Writer software, create a new document, and start typing content. At the same time, we can use various formatting tools provided by Writer to adjust the font, size, color, etc. of the text to make the document more beautiful. In addition, we can also insert elements such as pictures, tables, and charts to enhance the expressiveness of the document.

The following code example shows how to create a new document in Writer and insert a picture into it:

import org.apache.poi.xwpf.usermodel.*;

public class WriterExample {
   public static void main(String[] args) {
      // 创建一个新文档
      XWPFDocument document = new XWPFDocument();

      // 创建一个段落
      XWPFParagraph paragraph = document.createParagraph();

      // 插入一张图片
      XWPFRun run = paragraph.createRun();
      String imgFile = "image.jpg";
      int imgFormat = XWPFDocument.PICTURE_TYPE_JPEG;
      FileInputStream fis = new FileInputStream(imgFile);
      byte[] bytes = IOUtils.toByteArray(fis);
      fis.close();
      run.addPicture(new ByteArrayInputStream(bytes), imgFormat, imgFile, Units.toEMU(200), Units.toEMU(200));

      // 保存文档
      FileOutputStream fos = new FileOutputStream("document.docx");
      document.write(fos);
      fos.close();
   }
}

Through the above code example, we can see how to use Java to write a simple The program uses the apache.poi library and the API of the Writer software to realize the function of inserting a picture into the document.

In the Calc software of Kirin operating system, we can perform data analysis and processing to meet our needs at work.

Calc is a powerful spreadsheet software similar to Microsoft Excel. We can use Calc to process large amounts of data, conduct data analysis and modeling in order to make more accurate decisions.

The following code example shows how to use the API of Calc software to create a new spreadsheet in a Java program and fill in data:

import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.usermodel.*;

public class CalcExample {
   public static void main(String[] args) {
      // 创建一个新电子表格
      Workbook workbook = new XSSFWorkbook();
      Sheet sheet = workbook.createSheet("Sheet1");

      // 填充表格数据
      Row row = sheet.createRow(0);
      Cell cell = row.createCell(0);
      cell.setCellValue("姓名");

      row = sheet.createRow(1);
      cell = row.createCell(0);
      cell.setCellValue("张三");

      // 保存电子表格
      try (FileOutputStream fos = new FileOutputStream("workbook.xlsx")) {
         workbook.write(fos);
         fos.close();
      } catch (IOException e) {
         e.printStackTrace();
      }
   }
}

Through the above code example, we can understand How to use Java to write a simple program that uses the apache.poi library and the Calc software API to create a new spreadsheet and fill in data.

In addition to the two examples of Writer and Calc, the office software in Kirin operating system also includes Impress, etc. These software can meet our needs for making presentations at work.

To sum up, the office software in Kirin operating system, with its stable, safe and efficient characteristics, meets our work needs in word processing, data analysis and presentation production. Through the demonstration of code examples, we can more intuitively understand how to use the APIs of these software to implement various functions and improve work efficiency. With the continuous development and optimization of Kirin operating system, I believe that its office software will be more perfect and bring us more convenience and benefits.
