max and min in array?

[James Jones]

Hi, i think this might be a bit too easy for here, i am not sure.
but its not easy for me, lol
i have this code which prints out a simple array....right. but i cant figure out a way for it to print out the min, max, and mean...can i have some hints please....

 
public class ArrayDemo {
    public static void main(String[] args) {
        int[] anArray;        // declare an array of integers
        anArray = new int[10];// create an array of integers
        // assign a value to each array element and print 
        for (int i = 0; i < anArray.length; i++) {
            anArray[i] = i;
            System.out.print(anArray[i] + " ");
        }
        System.out.println();
    }
}

 public class ArrayDemo
{
public static void main(String[] args)
{
int[] anArray;        // declare an array of integers
anArray = new int[10];// create an array of integers
// assign a value to each array element and print
for (int i = 0; i < anArray.length; i++)
{
anArray[i] = i;
System.out.print(anArray[i] + " ");
}
int minValue = anArray[0];
int maxValue = anArray[0];
int sum = 0;
//Loop through the array to find the min, max and sum of all array elements
for (int i = 0; i < anArray.length; i++)
{
minValue = java.lang.Math.min(minValue, anArray[i]);
maxValue = java.lang.Math.max(minValue, anArray[i]);
sum += anArray[i];
}

//print out the values
System.out.println("\nminValue :" + minValue);
System.out.println("maxValue :" + maxValue);
System.out.println("sum :" + sum);

//divide the sum by the no of array elements to get the mean
float meanValue = (float)sum/anArray.length;
System.out.println("meanValue :" + meanValue);

}
} 

Hi,
I have added to your code, to find the max, min and mean of the array elements. Hope you find this helpful.
