如何在java中删除文件路径编码％20

Question

我打算在使用java的特定路径中创建一个xml文件。 问题是如果我给它的空间编码的文件路径是'％20'在空格中。 请帮我解决这个问题。由我给

文件路径 - “F：/备份文件/ testng2.xml”
编码后 - “F：/Backup%20Files/testng2.xml”

代码：

TransformerFactory transformerFactory = TransformerFactory.newInstance(); 
Transformer transformer = transformerFactory.newTransformer(); 
DOMSource source = new DOMSource(doc); 
StreamResult result = new StreamResult(new File("F:/Backup Files/testng2.xml"));  
transformer.transform(source, result); 
System.out.println("File saved successfully"); 

错误：

尝试增加.getAbsolutePath()您File，如下所示：

TransformerFactory transformerFactory = TransformerFactory.newInstance(); 
    Transformer transformer = transformerFactory.newTransformer(); 
    DOMSource source = new DOMSource(doc); 
    StreamResult result = new StreamResult(new File("F:/Backup Files/testng2.xml").getAbsolutePath());   
    transformer.transform(source, result); 
    System.out.println("File saved successfully");
