The following program demonstrates how to Find the Reverse of a Two Dimensional Array in Java.

Basically, here we create a 2 X 2 array by taking four integers as command line arguments. If the user doesn’t provide exactly four integers, the program shows an error message and exits. Otherwise, it creates a 2D array y using these numbers. Further, a new 2 X 2 array is created and the nested for loop inserts the elements of the original array into the new array in reverse order.

``````public class Exercise13
{
public static void main(String[] args) {
if(args.length!=4)
{
System.exit(0);
}
int[][] arr=new int[2][2];
int[][] arr1=new int[2][2];
int c=0;
for(int i=0;i<2;i++)
{
for(int j=0;j<2;j++)
{
arr[i][j]=Integer.parseInt(args[c]);
c++;
}
}

System.out.println("Original Array...");
for(int i=0;i<2;i++)
{
for(int j=0;j<2;j++)
{
System.out.print(arr[i][j]+" ");
}
System.out.println();
}
for(int i=0;i<2;i++)
{
for(int j=0;j<2;j++)
{
arr1[i][j]=arr[1-i][1-j];
}
System.out.println();
}

arr=arr1;
System.out.println("Reversed Array...");
for(int i=0;i<2;i++)
{
for(int j=0;j<2;j++)
{
System.out.print(arr[i][j]+" ");
}
System.out.println();
}
}
}``````
