5. Write a Java program to find the sum of each row and the sum of
   each column in a given matrix.

import java.util.Scanner;
public class Matrix
{
public static void main(String[]args)
{
int row =0;
int column =0;
int a[][]=null;
Scanner scan =new Scanner(System.in);
System.out.println("Enter row and column size: "");
row =scan.nextInt();
column =scan.nextInt();
a =new int[row][column];
System.out.println("Enter Matrix: "");
for(int i=0;i<=length;i++)
{
for(int j =0; j<=i;a[0].length;j++)

{

a[i][j]=scan.nextInt();
}
}
int rowsum;
int columnsum;
for(int i=0;i<=3;i++)
{
rowsum=0;
columnsum=0;
for(int j=0; j<=3;j++)
{

rowsum+= a[i][j];
columnsum+= a[j][i];
}
System.out.printl("row"+(i+1)+" sum = "+rowsum);
System.out.println("Column"+(i+1)+"" sum = "+columnsum);
}
scan.close();
