FilenameUtils sinfiga misol

IOTester.java
import java.io.IOException;
import org.apache.commons.io.FilenameUtils;

public static void main(String[] args) {
try {
//Using FilenameUtils
usingFilenameUtils();
} catch(IOException e) {
System.out.println(e.getMessage());
}
}

public static void usingFilenameUtils() throws IOException {
String path = "C:\\dev\\project\\file.txt";
System.out.println("Full Path: " +FilenameUtils.getFullPath(path));
System.out.println("Relative Path: " +FilenameUtils.getPath(path));
System.out.println("Prefix: " +FilenameUtils.getPrefix(path));
System.out.println("Extension: " + FilenameUtils.getExtension(path));
System.out.println("Base: " + FilenameUtils.getBaseName(path));
System.out.println("Name: " + FilenameUtils.getName(path));
String filename = "C:/commons/io/../lang/project.xml";
System.out.println("Normalized Path: " + FilenameUtils.normalize(filename));
}
}
Natija:
Full Path: C:\dev\project\
Relative Path: dev\project\
Prefix: C:\
Extension: txt
Base: file
Name: file.txt
Normalized Path: C:\commons\lang\project.xml
