Help with arrays

[Shawn Houston]

Ok i have a program that takes 4 orchards over a 5 year span. I need to get the average of each orchard. Which I have..now i need to get the Total of the 4 orchards for each of the 5 years..then the average for each year which I'm having a real trouble doing.

int arraySize, salesNum;
double amount; 
BufferedReader keyboard = new 
BufferedReader(new InputStreamReader(System.in)); 
 
int peach[][] = {{15,23,24,11,19}, {16,21,23,12,20}, {45,47,53,55,57}, {5,6,7,11,9}};
int i, j, total;
int [ ] orchard_total = new int [4];
int [ ] year_total = new int [5];
float average;
float[ ] orchard_avg = new float[4];
float [ ] year_avg = new float[5];
 
for(i = 0; i < 4; i++) {
for(j = 0; j < 5; j++)
orchard_total[i] += peach[i][j];
orchard_avg[i] = (float)(orchard_total[i] / 5.0);
}
System.out.println("Orchard Number\t\t\tAverage Production");
for(i = 0; i < 4; i++) {
System.out.print(i+1 + "\t\t\t\t\t");
System.out.println(orchard_avg[i]);
}
}
}
 

I just can't seem to get the totals for each seperate year and the averages.
What i thinking is I have to:
for(i = 0; i < 4; i++) {
for(j = 0; j < 5; j++)
year_total[i] += peach[0][0] +peach[0][1] + peach[0][2] + peach[0][3];
year_avg[i] = (float)(year_total[i] / 4.0);

For each consecutive year..but when i do that it adds both years then averages them. Not sure where I'm going wrong here nor how to put all the years into 1 for statement if its even possible.

Hi,

Something a little different but a little the same:

 
for(int x = 0; x < 5; x++) {
 
for(int y = 0; y < 4; y++) {
 
total += peach[y][x];
 
                       ...
