This example demonstrate how to use the method
Path java.nio.file.Path.resolve(Path other) to resolve the given path against this path.
package javafx_niofile;
import java.io.File;
import java.nio.file.Path;
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.layout.VBox;
import javafx.stage.FileChooser;
import javafx.stage.Stage;
/**

public class JavaFX_NIOFile extends Application {
Label label;
@Override
public void start(Stage primaryStage) {
Button btnLoad = new Button();
btnLoad.setText("Load File");
btnLoad.setOnAction(btnLoadEventListener);
label = new Label();
VBox rootBox = new VBox();
rootBox.getChildren().addAll(btnLoad, label);
Scene scene = new Scene(rootBox, 400, 350);
primaryStage.setTitle("java-buddy.blogspot.com");
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
EventHandler<ActionEvent> btnLoadEventListener
= new EventHandler<ActionEvent>(){
@Override
public void handle(ActionEvent t) {
FileChooser fileChooser = new FileChooser();
//Set extension filter
FileChooser.ExtensionFilter extFilter
= new FileChooser.ExtensionFilter("ALL files (*.*)", "*.*");
fileChooser.getExtensionFilters().add(extFilter);
//Show open file dialog, return a java.io.File object
File file = fileChooser.showOpenDialog(null);
//obtain a java.nio.file.Path object
Path path = file.toPath();
Path parentPath = path.getParent();
Path partialPath = path.getFileName();
Path resolvedPath = parentPath.resolve(partialPath);
String fileInfo = "parent = " + parentPath + "\n" +
"partial path = " + partialPath + "\n" +
"resolve Path = " + resolvedPath;
