Question

Program sort matrix in descending order.

```				```
Matrix =  [5, 2, 7]
[9, 6, 4]
[3, 8, 1]

SORTED MATRIX
9  8  7
6  5  4
3  2  1
```
```

Code

```				```
import java.util.Scanner;
public class SortMatrixInDescendingOrder
{
public static void main(String[] args)
{
int row=0, col=0,i=0,j=0,k=0,l=0,temp=0;
int arr[][];

Scanner sc=new Scanner(System.in);
System.out.println("ENTER THE ROW OF MATRIX");
row=sc.nextInt();
System.out.println("ENTER THE COLUMN OF MATRIX");
col=sc.nextInt();

arr=new int[row][col];
System.out.println("ENTER THE ELEMENTS IN MATRIX");
for(i=0;i< row;i++)
{
for(j=0;j< col;j++)
{
arr[i][j]=sc.nextInt();
}
}

System.out.println("UNSORTED MATRIX ");
for(i=0;i< row;i++)
{
for(j=0;j< col;j++)
{
System.out.print(arr[i][j]+" ");
}
System.out.println();
}

for(i=0;i< row;i++)
{
for(j=0;j< col;j++)
{
for(k=0;k< row;k++)
{
for(l=0;l< col;l++)
{
if(arr[i][j]> arr[k][l])
{
temp=arr[i][j];
arr[i][j]=arr[k][l];
arr[k][l]=temp;
}
}
}

}

}

System.out.println("SORTED MATRIX ");
for(i=0;i< row;i++)
{
for(j=0;j< col;j++)
{
System.out.print(arr[i][j]+" ");
}
System.out.println();
}

}
}
