使用java代码编写编写一段检查ppt或者是ppt文件的是否有动画效果,如果一个动画效果的时间分数不是递增的返回false

这里提供一种基于Apache POI的实现方式,具体实现如下:
```java
import java.io.FileInputStream;
import java.io.IOException;
import org.apache.poi.sl.usermodel.Slide;
import org.apache.poi.xslf.usermodel.XMLSlideShow;
import org.apache.poi.xslf.usermodel.XSLFShape;
import org.apache.poi.xslf.usermodel.XSLFSlide;
import org.apache.poi.xslf.usermodel.XSLFTextShape;
import org.openxmlformats.schemas.drawingml.x2006.main.CTTimeNodeList;
public class PPTAnimationChecker {
public static boolean check(String filePath) {
boolean isIncreasing = true;
try (FileInputStream fis = new FileInputStream(filePath);
XMLSlideShow ppt = new XMLSlideShow(fis)) {
for (XSLFSlide slide : ppt.getSlides()) {
if (slide.getSlideShow().getPageSize().equals(slide.getSlideShow().getPageSize())) {
for (XSLFShape shape : slide.getShapes()) {
if (shape instanceof XSLFTextShape) {
CTTimeNodeList timeNodeList = ((XSLFTextShape) shape).getCTShape().getNvSpPr().getCNvPr().getAnimPr().getTnLst();
if (timeNodeList.sizeOfTnArray() > 0) {
double prevTime = -1;
for (int i = 0; i < timeNodeList.sizeOfTnArray(); i++) {
double currTime = timeNodeList.getTnArray(i).getDur().getVal() / 60000.0;
if (prevTime > currTime) {
isIncreasing = false;
break;
}
prevTime = currTime;
}
}
}
}
}
}
} catch (IOException e) {
e.printStackTrace();
}
return isIncreasing;
}
public static void main(String[] args) {
boolean result = check("/path/to/ppt/file.pptx");
System.out.println(result);
}
}
```
具体思路是通过Apache POI库打开PPT文件,遍历每一页,对于每个文本框检查其是否有动画效果,若有则检查动画效果的时间分数是否递增,如果不是则返回false。
