Is there a faster way to do this?

import java.io.*;
import javax.swing.*;

public class Main {
    public static void main(String[] args) {
       
        String[] loweralpha = new String[26];
        String[] upperalpha = new String[26];
        String[] numbers = new String[10];
        
        loweralpha[0] = "a";
        loweralpha[1] = "b";
        loweralpha[2] = "c";
        loweralpha[3] = "d";
        loweralpha[4] = "e";
        loweralpha[5] = "f";
        loweralpha[6] = "g";
        loweralpha[7] = "h";
        loweralpha[8] = "i";
        loweralpha[9] = "j";
        loweralpha[10] = "k";
        loweralpha[11] = "l";
        loweralpha[12] = "m";
        loweralpha[13] = "n";
        loweralpha[14] = "o";
        loweralpha[15] = "p";
        loweralpha[16] = "q";
        loweralpha[17] = "r";
        loweralpha[18] = "s";
        loweralpha[19] = "t";
        loweralpha[20] = "u";
        loweralpha[21] = "v";
        loweralpha[22] = "w";
        loweralpha[23] = "x";
        loweralpha[24] = "y";
        loweralpha[25] = "z";    
    }
}

Want to create 3 arrays, but surely there is a shorter way of writing this? Can't see how I could do it using a for loop.

I don't know a lot about java, but would the below not work?

loweralpha[] = ["a","b",..."y","z"]

Yeah looking at it that's probably the easiest solution here.

Are you looking for the ability to check if a single letter is say upper case?

I'm trying to exhaustivley search all possible combinations of letters.
