I'm sure people would be happy to help you, including me. But only if you show some attempt at the problems yourself.

Ok I did the first one. I'm stuck on number 2. Here's what I think:
If rows = columns
then, print out regular.
else rows does not = columns
then, printout irregular.

and for number 3, im really confused....

What he means is post what code you have written thus far. We are not here to spoon feed you, and will not do your work for you.

This is number 3:

import java.util.Random;
import java.util.Scanner;
public class concatArray {
private static Random r = new Random();
private static String letter;
private static StringBuffer array = new StringBuffer();
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int arrayRow, arrayColumn, random;
String find[][];

System.out.println("Enter the amount of Rows in the array, then Columns: ");
arrayRow = input.nextInt();
arrayColumn = input.nextInt();

find = new String[arrayRow][arrayColumn];

for(int x = 0; x < find.length; x ++){
for(int i = 0; i < find[x].length; i ++){
random = r.nextInt(10) + 1;
getLetter(random);
find[x][i] = letter;
}
}
concatArray(find);
}
private static void concatArray(String[][] find) {
for(int x = 0; x < find.length; x++){
for(int i = 0; i < find[x].length; i++){
array = array.append(find[x][i] + ", ");
}
}
System.out.print(array);
}
private static void getLetter(int i) {
switch(i){
case 1: letter = "A"; break;
case 2: letter = "B"; break;
case 3: letter = "C"; break;
case 4: letter = "D"; break;
case 5: letter = "E"; break;
case 6: letter = "F"; break;
case 7: letter = "G"; break;
case 8: letter = "H"; break;
case 9: letter = "I"; break;
case 10: letter = "J"; break;
default: letter = "Unknown"; break;
}

}

}


*Not in the code:
I used String Buffer because I didn't want to concat everything together and by the way concat means you add to strings to one another for example:

String s1 = "a";
String s2 = "b";
String s3 = s1.concat(s2);
------------------------------------------------------------------------------------------------------
Also stringbuffer basically is essentially a string except unlike a string joins strings together instead of just deleting a string and creating a new one every time you make a change to a string. Therefore StringBuffer is just way easier to use instead of concat.
