I can't find my error here?

import java.util.Scanner;
    class Code {
            public static void main (String[] args) {
                    Scanner a = new Scanner (System.in);
                    System.out.println("Please, Enter Array Size : ");
                    int size = a.nextInt();
                    double[] arr = new double[size];
                    System.out.println("Enter Array elements : ");
                    for (int i = 0; i < size; i++) {
                            arr[i] = a.nextDouble();
                    int max = arr[0];
                    int min = arr[0];
                    for (int i = 1; i < size; i++) {
                            if (max < arr[i]) {
                                    max = arr[i];
                            if (min > arr[i]) {
                                    min = arr[i];
                    System.out.println("maximum is : " +max);
                    System.out.println("minimum is : " +min);

Your are getting error because of different data types. The array you have defined is of double data type, but the min and max variables are of int type. So make them of double data type like:

double min,max;

If you want to keep min and max of int data type then you need to typecast the array element like:


but it is not recommended.

  • ohhooo!!! Thank you very much. I did it on 'C', but there no error. I shift few day's ago in java, & i have faced many small problem,which is getting bigger for me! In that case i was thinking 'C' is better then 'java' :) – Lidan Suidan Jan 11 at 6:45
