Question

How to get the frequency of smallest array value in Java

Answer 1

public class MyClass {
    public static int minArr(int[] arr) {
        int minval = arr[0];   
        for (int i = 1; i < arr.length; i++) {
            if (arr[i] < minval) {
                minval = arr[i]; 
            }
        }
        return minval;
    }
    public static void main(String args[]) {
        int[] arr = new int [] {6, 4, 4, 7, 3, 3, 3, 5, 5, 7, 8, 3, 4, 3};    
        
        int frequency = 0;
        
        int min = minArr(arr);
        
        for (int i = 1; i < arr.length; i++) {
            if (arr[i] == min) {
                frequency++;
            }
        }
        System.out.println(frequency);
    }
}

Answer 2

import java.util.Arrays;

public class MyClass {
    public static void main(String args[]) {
        int[] arr = new int [] {6, 4, 4, 7, 3, 3, 3, 5, 5, 7, 8, 3, 4, 3};  
        
        int frequency = 0;
        
        int min = Arrays.stream(arr).min().getAsInt();
        
        for (int i = 1; i < arr.length; i++) {
            if (arr[i] == min) {
                frequency++;
            }
        }
        System.out.println(frequency);
    }
}
