/*Write a Java program that will take the number of rows and columns from the user and create a 2D array by taking integer numbers from the user. Print the 2D array.  Finally, create a 1D array by flattening the 2D array.

Sample Input           Sample Output 
row = 2                 2D Array:
column = 3              1 2 3
1                       4 5 6
2
3                       1D Array:
4                       1 2 3 4 5 6
5
