Java从一个文件夹中搜索文件名 [英] Java searching file name from the one folder

问题描述

我正在学习Java，我不太确定搜索文件的方法。我想构建返回文件名的函数（文件名应以 star 开头，以 .txt 结尾）

I am studying Java and I am not really sure the way to searching file. I would like to build the function which returning file names ( the files name should begin with star and end with .txt)

例如，在文件夹中我们有一些带有文件的Java源文件。例如，文件：

For example, in the folder we have Java source file with some file. For example, files:

• 1.txt


• 2.txt


• 4.txt


• start.txt


• star.txt


• onstart.txt


• starton.txt


• myjava.java

• 1.txt
• 2.txt
• 4.txt
• start.txt
• star.txt
• onstart.txt
• starton.txt
• myjava.java

然后我想得到 start.txt ， star.txt & starton.txt

Then I would like to get the start.txt, star.txt & starton.txt

我一直在寻找 FilenameFilter 但我无法找到找到文件的好方法。有没有人知道查找文件的方法？

I was looking for the FilenameFilter but I wasn't able to find to good way to find file. Does any one know the way to find files?

推荐答案

// You'll need this import: import java.io.File;

File folder = new File("C:/Folder_Location");
// gets you the list of files at this folder
File[] listOfFiles = folder.listFiles();
// loop through each of the files looking for filenames that match
for(int i = 0; i < listOfFile.length; i++){
    String filename = listOfFiles[i].getName();
    if(filename.startsWith("Stuff") && listOfFiles[i].getName().endsWith("OtherStuff")){
        // do something with the filename
    }
}
