I'm relatively new to programming, and recently I've been working on a random password generator. The problem I'm having is that, for some reason I can't figure out, the passwords generated aren't the right size or the right characters(In fact, all it produces is a password full of numbers).

Code:
/*
 * This program is used to generate a password using both lower case and upper case
 * letters, numbers, and symbols
 *
 * Currently, this program kinda works. It does not create a password with the right number of characters
 * or the right characters
 */

package passwordgenerator;
import java.util.*;
import java.io.*;

public class Main
{

    public static void main(String[] args) throws IOException
    {
        File file = new File("Passwords.txt");     
        BufferedWriter output = new BufferedWriter(new FileWriter(file));       
        Scanner scan = new Scanner(System.in);

        Random generator = new Random(); 

        String string;

        int passSize = 0;       //The size of the password

        //The array that contains the possible characters for the password(lower case/upper case/special characters/numbers)
        int[] lArray = {'a', 'b', 'c', 'd', 'e', 'f', 
            'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o'
                , 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 
                'x', 'y', 'z', 'A', 'B', 'C', 'D', 'E', 'F', 
                'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 
                'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z', '1',
                '2','3','4','5','6','7','8','9','0', '!', '@', '#', '$', '%', '+', '-' };

        System.out.println(lArray.length-1);        //Not sure why I have this. Probably a test output to get the last index of lArray

        System.out.println("Size of password: ");
        passSize = scan.nextInt();

        int[] pArray = new int[passSize];       //The array that will contain the password

        //This for loop creates the password
        for(int i = 0; i < passSize; i++)
        {
            pArray[i] = lArray[generator.nextInt(lArray.length)];
        }

        //System.out.println("Website/Program password is for");        //This was meant to add the name of what the password was for.
                                                                        //Currently not working

        string = scan.nextLine() + "";

       
        for(int i = 0; i < pArray.length; i++)
        {
            string += pArray[i];
        }

        output.write(string);       
        output.close();   
        
        System.out.println("Password generated. Saved in Passwords.txt");


    }

}
I think it has something to do with the first for loop, but I'm not sure what
