In this source code example, we will write the Java program to demonstrate how to remove even integers from a given Array.

Remove Even Integers from an Array

public class RemoveEvenInteger {

   public static void printArray(int[] arr) {
      int n = arr.length;
      for (int i = 0; i < n; i++) {
         System.out.print(arr[i] + " ");
      }
      System.out.println();
   }

   public static int[] removeEven(int[] arr) {
      int oddCount = 0;
      for (int i = 0; i < arr.length; i++) {
         if (arr[i] % 2 != 0) {
            oddCount++;
         }
      }
      int[] result = new int[oddCount];
      int idx = 0;
      for (int i = 0; i < arr.length; i++) {
         if (arr[i] % 2 != 0) {
            result[idx] = arr[i];
            idx++;
         }
      }
      return result;
   }

   public static void main(String[] args) {
      int[] arr = { 3, 2, 4, 7, 10, 6, 5 }; // 3, 7, 5
      printArray(arr);
      int[] result = removeEven(arr);
      printArray(result);
   }
}

Output:

3 2 4 7 10 6 5 
3 7 5
