Following program is used to find sum of array elements :
import java.util.*;
public class Gndec {
public static void main(String[] nt)
{ Scanner input=new Scanner(System.in); //for user input
System.out.println("Enter Number of Elements");
int n=input.nextInt(); //no of elements
int[] a=new int[n]; //allocating space for n elements
System.out.println("Enter The Elements");
for(int i=0;i<n;i++)
{
a[i]=input.nextInt(); //storing all values
}
int sum=0;
for(int i=0;i<n;i++)
{
sum=sum+a[i];
}
System.out.println("Sum of Elements="+sum);
}
}
Output:

public static void main(String[] nt)

System.out.println("Enter Number of Elements");
int n=input.nextInt(); //no of elements
int[] a=new int[n]; //allocating space for n elements

for(int i=0;i<n;i++)
{

}
int sum=0;
for(int i=0;i<n;i++)
{
sum=sum+a[i];
}
System.out.println("Sum of Elements="+sum);
}
}
Output:
