Ⅰ 學習java的PPT課程

java的ppt，不知道你要這個有什麼用
如果你是個新手那麼ppt不建議看，一般人家教程的ppt都是概覽全局的知識，不是很詳細，還不如買本書去看
或者是去看視頻、網路下java多的 很的視頻
如果樓主是在不想自己找，推薦去下淘寶直接損失java視頻，幾塊錢可以買幾十G的學習資料。

Ⅱ 怎樣用JAVA做幻燈片

可以是可以哇，不過要想做的好看那就得下大功夫了，看你用什麼方式做，BS網頁形式的比較好做，如果是CS客戶端做的話就不太好做了，因為java客戶端本來就很醜，做出來也會很醜咯

Ⅲ java 怎麼把ppt轉html

ppt保存為html文件的方法：
用c#可以輕松實現轉換：

using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
using PPT = Microsoft.Office.Interop.PowerPoint;
using System.Reflection;

namespace WritePptDemo
{
class Program
{
static void Main(string[] args)
{
string path; //文件路徑變數

PPT.Application pptApp; //Excel應用程序變數
PPT.Presentation pptDoc; //Excel文檔變數

PPT.Presentation pptDoctmp;

path = @"C:\MyPPT.ppt"; //路徑
pptApp = new PPT.ApplicationClass(); //初始化

//如果已存在，則刪除
if (File.Exists((string)path))
{
File.Delete((string)path);
}

//由於使用的是COM庫，因此有許多變數需要用Nothing代替
Object Nothing = Missing.Value;
pptDoc = pptApp.Presentations.Add(Microsoft.Office.Core.MsoTriState.msoFalse);
pptDoc.Slides.Add(1, Microsoft.Office.Interop.PowerPoint.PpSlideLayout.ppLayoutText);

string text = "示例文本";

foreach (PPT.Slide slide in pptDoc.Slides)
{
foreach (PPT.Shape shape in slide.Shapes)
{
shape.TextFrame.TextRange.InsertAfter(text);
}
}

//WdSaveFormat為Excel文檔的保存格式
PPT.PpSaveAsFileType format = PPT.PpSaveAsFileType.ppSaveAsDefault;

//將excelDoc文檔對象的內容保存為XLSX文檔
pptDoc.SaveAs(path, format, Microsoft.Office.Core.MsoTriState.msoFalse);

//關閉excelDoc文檔對象
pptDoc.Close();

//關閉excelApp組件對象
pptApp.Quit();

Console.WriteLine(path + " 創建完畢！");

Console.ReadLine();

string pathHtml = @"c:\MyPPT";

PPT.Application pa = new PPT.ApplicationClass();

pptDoctmp = pa.Presentations.Open(path, Microsoft.Office.Core.MsoTriState.msoTrue, Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoFalse);
PPT.PpSaveAsFileType formatTmp = PPT.PpSaveAsFileType.ppSaveAsHTML;
pptDoctmp.SaveAs(pathHtml, formatTmp, Microsoft.Office.Core.MsoTriState.msoFalse);
pptDoctmp.Close();
pa.Quit();
Console.WriteLine(pathHtml + " 創建完畢！");
}
}
}
這樣在創建完畢後就可以在c盤找到MyPPT了。

Ⅳ 求畢向東java基礎視頻的PPT

我這有一份PDF版本的

Ⅳ Java如何調用PPT當前頁碼

XWPFDocument docx = new XWPFDocument(POIXMLDocument.openPackage(電月度例會會議紀要.docx)); int pages = docx.getProperties().getExtendedProperties().getUnderlyingProperties().getPages();//總頁數 int wordCount = docx.getProperties().getExtendedProperties().getUnderlyingProperties().getCharacters();// 忽略空格的總字元數 另外還有getCharactersWithSpaces()方法獲取帶空格的總字數。 System.out.println (pages= + pages + wordCount= + wordCount);} public static void parse97() throws Exception { WordExtractor doc = new WordExtractor(new FileInputStream(電月度例會會議紀要.doc));

Ⅵ java 把office word,ppt轉化為圖片

從一個大神那裡學來的，已測試無誤
package com;

import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;

public static void main(String[] args) {
// 讀入PPT文件
File file = new File("D:\\UPH.ppt");
doPPTtoImage(file);
}

public static boolean doPPTtoImage(File file) {
boolean isppt = checkFile(file);
if (!isppt) {
System.out.println("The image you specify don't exit!");
return false;
}
try {
FileInputStream is = new FileInputStream(file);
SlideShow ppt = new SlideShow(is);

for (int l = 0; l < rtruns.length; l++) {

rtruns[l].setFontName("宋體");
}
}
BufferedImage img = new BufferedImage(pgsize.width, pgsize.height,

Graphics2D graphics = img.createGraphics();
graphics.setPaint(Color.BLUE);
graphics.fill(new Rectangle2D.Float(0, 0, pgsize.width, pgsize.height));
slide[i].draw(graphics);

// 這里設置圖片的存放路徑和圖片的格式(jpeg,png,bmp等等),注意生成文件路徑
File path = new File("D:/images");
if (!path.exists()) {
path.mkdir();
}
FileOutputStream out = new FileOutputStream(path + "/" + (i + 1)
+ ".jpg");
javax.imageio.ImageIO.write(img, "jpeg", out);
out.close();
}
System.out.println("success!!");
return true;
} catch (FileNotFoundException e) {
System.out.println(e);
} catch (IOException e) {
}
return false;
}

// function 檢查文件是否為PPT
public static boolean checkFile(File file) {

boolean isppt = false;
String filename = file.getName();
String suffixname = null;
if (filename != null && filename.indexOf(".") != -1) {
suffixname = filename.substring(filename.lastIndexOf("."));
if (suffixname.equals(".ppt")) {
isppt = true;
}
return isppt;
} else {
return isppt;
}
}

}

Ⅶ 求一份Java程序設計的ppt

你是學生嗎？做什麼用的？

Ⅷ 我想做一個介紹java項目的ppt文件,我想知道該如何介紹會好,比如說用到的技術,實現的功能等等

1、需求分析：從功能入手講起，使用用例圖，講清楚用戶需求是什麼；
2、概要設計：根據功能擴展到框架結構設計，這一部分主要是模塊設計；
3、詳細設計：說一說Java的類結構，最好用UML類圖說明
4、重點難點：撿幾個具體的重要技術或演算法談一下
5、運行結果：介紹項目的運行環境以及運行截圖
6、擴展性分析；談談項目的可擴展性與未來展望

Ⅸ eclipse-java讀取ppt

java中讀取ppt的實現方法如下：

// s = rf.readPDF("E:/memcached全面剖析.pdf");
// s = rf.readEXCEL("E:/副本工作量及成本模板.xls");
// s = rf.readEXCEL2007("E:/功能點估算方案.xlsx");
// s = rf.readWORD("E:/pms中文.doc");
// s = rf.readWORD2007("E:/功能點估算方法.docx");
//s = rf.readPPT("E:/精細化管理信息系統項目匯報v1.0.ppt");
s = rf.readPPT2007("e:/精細化管理信息系統項目匯報v1.0.pptx");
System.out.println(s);
}
