Finding Files with particular extension or Pattern in Java
Often, to find a file with a particular extension or naming pattern within a directory, we might implement as below:
// The directory which search would be conducted
File directoryForSearch = new File("C:\folder");
// This may not be the best way to accomplish the task, please bear me with it
File[] allFile = directoryForSearch.listFiles();
File[] resultFile = new File[allFile.length];
int resultCount = 0;
// loop thru the list of files to find the required files
for(int i=0; i<allFile.length; i++)
{
if(allFile[i].getName().matches(".*\\.java")
{
resultFile[resultCount] = allFile[i];
resultCount++;
}
}
