Thread: Help with an array please!

Thanks for the link and the reply Copeg. I have an idea of how to define arrays, but my problem is making them so that the user can input the amounts of rows/columns (they will always be the same). I am in my last semester of school (digital forensics) and this is the only thing that I have taken that I just can't get. I am completely lost on pretty much the whole thing.

I got a Ton of help on array lists before from some extremely generous and patient people. Maybe you can use that as an example for learning how to do them.

This support is only for you as you are totally begginer. There are definitely other ways to handle, but for your level i suggest:
1. Declare an array of huge size.
2. Get a numberic value from user.
3. Limit your array to that value.

Thanks for the tip. I am completely not getting this Java stuff at all, which is just further frustrating me. I can't seem to figure this program out AT ALL!!! This is all that I have so far

import java.util.Scanner;

//Begin Class Main
public class Main {

//Begin Main Method
public static void main(String[] args) {

int arraySize;
int rArray[row][col];


Scanner input = new Scanner (System.in);

System.out.print("Enter the number of rows & columns (they will be "
+ "the same): ");
arraySize = input.nextInt();

rArray = new int[row][col];

}
public static void showArray (int[] array){

Like I said before, the array size is determined by the user and the rows and columns will always be the same therefor I only need to get one number from them. Yet I can't figure any of it out.


} //End Main Method

} //End Class Main

int rArray[row][col];

What are row and col? Do you declare a 1d array the same way?

int[size] numbers;

Does that look right?

1. Put your code in code tags.
2. Indent your code with proper IDE. I believe you are using wordpad somewhat...
3.

const row=100;
const int col=100;
int [row]Array[col];
//Get input for rows first.
//Get input for columns.
for(int i=0;i<row;i++)
{
     for(int j=0;j<col;j++)
     {
       array[i][j]=whatever values are;
      }
}

If you are going to spoonfeed code at least make it correct Java code.

Mixed code and pseudocode. So, i don't try to spoonfeed him.

Well whatever you posted is doing motre harm than good. From experience I have seen clueless n00bs simply copy and paste code into their program and then cannot understand why it doesn't work.

int [row]Array[col];

The worse you have done is to perpetuate their misunderstanding of how to declare a 2D array. My post above (while I could have just given them the correct code) was to prompt them to think about how to correct it themselves.

Yeah that's my bad.
I correct it.

int [][]array=new int[row][col];

Peace.
