I know this must be very simple but i don't know how to do it....
public class Program07
{
/*
Print the next Matrix
1 2 3 4 5 6 7 8 9 10
2 4 6 8 10 12 14 16 18 20
3 6 9 12 15 18 21 24 27 30
4 8 12 16 20 24 28 32 36 40
5 10 15 20 25 30 35 40 45 50
6 12 18 24 30 36 42 48 54 60
7 14 21 28 35 42 49 56 63 70
8 16 24 32 40 48 56 64 72 80
9 18 27 36 45 54 63 72 81 90
10 20 30 40 50 60 70 80 90 100
*/
public static void main(String[] args)
{
for (int i = 1; i <= 10 ; ++i)
{
int j = 1;
while ( j <= 10 )
{
if( i * j <= 9)
{
System.out.print( " " + i * j );
}
else
{
System.out.print( " " + i * j );
}
++j;
}
System.out.println("");
}
}
}
This programs prints this:
1 2 3 4 5 6 7 8 9 10
2 4 6 8 10 12 14 16 18 20
3 6 9 12 15 18 21 24 27 30
4 8 12 16 20 24 28 32 36 40
5 10 15 20 25 30 35 40 45 50
6 12 18 24 30 36 42 48 54 60
7 14 21 28 35 42 49 56 63 70
8 16 24 32 40 48 56 64 72 80
9 18 27 36 45 54 63 72 81 90
10 20 30 40 50 60 70 80 90 100
What i have to do is:
1.Show the result of the addition of every row
2.Show the result of the addition of every row
3.And the final result of the addition of all the matrix...
THanks in advance....
