Bro how to save a string "welcome"as a char in 2d array lik" w-a[0] [0] " and so on..

[laxayaboi]

for the second for loop why do we write j<a[0].length instead of j< a.length

[Ryderdie]

if using r in the i for-loop and c in the j for-loop produces the same result, what is the purpose of "a.length" or "a[0].length"?
I am new to the language Java and am genuinely curious. Great video though, very informative.


import java.util.Scanner;
import java.util.ArrayList;
import java.util.Arrays;
public class Main {

public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int r = scanner.nextInt();
int c = scanner.nextInt();
int[][] array = new int[r][c];
for (int i = 0; i < r; i++) {
for (int j = 0; j < c; j++) {
array[i][j] = scanner.nextInt();
}
}

for (int i = 0; i < r; i++)
{
for (int j = 0; j < c; j++)
{

}
System.out.println();
}
}
}

What does the "a" represent?
