Create a 2D array of a size that is decided by user input - the first number being the number of rows and the second number being the number of columns. Allow the user to fill the array with integers of their choice code example
Example 1: how to fill a 2d array in java
int rows = 5, column = 7;
int[][] arr = new int[rows][column];
for (int row = 0; row < arr.length; row++)
{
for (int col = 0; col < arr[row].length; col++)
{
arr[row][col] = 5;
}
}
Example 2: declare matrix in java
int[][] multi = new int[5][];
multi[0] = new int[10];
multi[1] = new int[10];
multi[2] = new int[10];
multi[3] = new int[10];
multi[4] = new int[10];
