Question

如题所述

Answer 1

public static void main(String[] args) {
        
        int num=0;
        int[] arr=new int[]{1,3,4,5,6,7,8,9,0,12,13};
        for (int i = 0; i < arr.length; i++) {
            if (arr[i]%2!=0) {
                num++;
            }
        }
        System.out.println(num);
    }

Answer 2

public class Test {

public static int oddCount(int[] arr){

int count = 0;

for(int i : arr){

if(i%2!=0){

count++;

}

}

return count;

}

public static void main(String[] args){

int[] arr ={0,1,3,4,5,6,7};

System.out.println(Test.oddCount(arr));

}

}
