Java Minimum and Maximum values in Array

Question

My code does not give errors, however it is not displaying the minimum and maximum values. The code is:

Scanner input = new Scanner(System.in);

int array[]          


        

Answer 1

I have updated your same code please compare code with your's original code :

public class Help {

public static void main(String args[]){
    Scanner input = new Scanner(System.in);

    int array[] = new int[10];

    System.out.println("Enter the numbers now.");

    for (int i = 0; i < array.length; i++) {
        int next = input.nextInt();
        // sentineil that will stop loop when 999 is entered
        if (next == 999) {
            break;
        }
        array[i] = next;
    }

    System.out.println("These are the numbers you have entered.");
    printArray(array);

    // get biggest number
    System.out.println("Maximum: "+getMaxValue(array));
    // get smallest number
    System.out.println("Minimum: "+getMinValue(array));
}

// getting the maximum value
public static int getMaxValue(int[] array) {
    int maxValue = array[0];
    for (int i = 1; i < array.length; i++) {
        if (array[i] > maxValue) {
            maxValue = array[i];
        }
    }
    return maxValue;
}

// getting the miniumum value
public static int getMinValue(int[] array) {
    int minValue = array[0];
    for (int i = 1; i < array.length; i++) {
        if (array[i] < minValue) {
            minValue = array[i];
        }
    }
    return minValue;
}

//this method prints the elements in an array......
//if this case is true, then that's enough to prove to you that the user input has  //been stored in an array!!!!!!!
public static void printArray(int arr[]) {
    int n = arr.length;

    for (int i = 0; i < n; i++) {
        System.out.print(arr[i] + " ");
    }
}
}
