JFileChooser with Button

[Lund01]

Hi everyone,

I am making a program that has multiple buttons. And now I would like when you click on button1 that a JFileChosser opens and that the selected file is read bij the program.
Now I have made a GUI with buttons and stuff, but I don't get my JFileChooser working. I program Java for a while now, but I never realy made a GUI before.
So I hope somebody can help me with my JFileChooser.

This is a part of my code that needs to read in a file.

// Create JFileChoosers to import files. 
JFileChooser chooser1 = new JFileChooser();

	// Make that the buttons do a certain action when you press one. 
	public void actionPerformed(ActionEvent e) {
		// Open a window where you can select a file1. 
		if (e.getSource() == button1) {
			chooser1.showOpenDialog(null); 
			// Get file 1. 
			java.io.File file1 = chooser1.getSelectedFile(); 
			//Create Scanner. 
			Scanner inputFile1 = new Scanner(file1);

			//
	               while (inputFile1.hasNext()) {
                                System.out.println(inputFile1.nextLine()); 
			
			}
			// Close file1. 
			inputFile1.close(); 
		}
		// Open a window where you can select a file2. 
		else if (e.getSource() == button2) {
			//commend
		}
		//
		else if (e.getSource() == button3) {
			//commend
		}
		else if (e.getSource() == button4) {
			//commend
		}
		// Close/exit the program. 
		else if (e.getSource() == button5) {
			System.exit(0); 
		}
		else if (e.getSource() == button6) {
			// Save file. 
		}
	}

Now I get this message:
Unhandled exception type FileNotFoundException at the text: new Scanner(file1).

But if I do that I get the Scanner inputFile1 = newScanner(file1); like this:

			try {
				inputFile1 = new Scanner(file1);
			} catch (FileNotFoundException e1) {
				// TODO Auto-generated catch block
				e1.printStackTrace();
			}

But then the problem is again that I can't use code from the while loop part in the try catch.

I figured out the problem.
For anyone who has the same problems as me:

			try {
				Scanner inputFile1 = new Scanner(file1); 
				while (inputFile1.hasNext()) {
					System.out.println(inputFile1.nextLine()); 
					
				}	
			} catch (Exception r) {
				System.out.println("Error");
			}

chooser1.showOpenDialog(this);

this represents the current object any Container object. Null don't work. I think so.

If your JFrame object is like JFrame f=new JFrame();

then, chooser1.showOpenDialog(f);

Which has nothing to do with the question in hand, which the OP managed to answer on their own.

I'm considering it already.

There should be some base for the JFileChooser to come i think so.

You can use jf.showOpenDialog(baseobj);

where baseobj may be a JFrame
