How can I access into arrays and add them each other then divide them?
example:
int[] a = {1,2,3,4};
now I want to add 1+2+3+4
Thanks in advance for the help
Can you help me with java?

Use the length property to determine the size of the array. Use [] notation to access an element. Use a for loop to add them up.
for (int i = 0; i < a.length; i++)
{
sum += a[i];
}
for (int i = 0; i < a.length; i++)
{
sum += a[i];
}

you can create an intermediate int
int tempValue = 0
foreach(var item in a)
{
tempValue = item + tempValue;
}
int devidedValue = tempValue/a.Count();
int tempValue = 0
foreach(var item in a)
{
tempValue = item + tempValue;
}
int devidedValue = tempValue/a.Count();

To access the nth object in array "a", use a[n]
To access every object in the array, use a "for" loop, incrementing n.
int sum = 0;
for (int i = 0; i < a.length; i++)
sum += a[i];
