heres the code which does exactly what u want. u may modify it so that
it looks better eg aray sizes should be hardcoded etc

the code is displays the output  on the standard outout which is the
console.

public class AddArray
{
public static void main(String[] args)
{
int a[]= {1,2,3,4,5};
int b[]= {9,2,4,7,1};

/* I want to add  this whole array  to my final  output will be

10, 4, 7, 11, 6
*/

int c[] = new int[5];
for (int i = 0; i < 5; i++)
{
c[i] = a[i] + b[i];

}

for (int i = 0; i < 5; i++) System.out.println(c[i]);

}
}
