Java Exercises: Move every positive number to the right and every negative number to the left of a given array of integers

Java Basic: Exercise-165 with Solution

Write a Java program to move every positive number to the right and every negative number to the left of a given array of integers.

Sample Solution:

Java Code:

import java.util.*;
public class Solution {
 public static int[] split_sorting_array(int[] nums) {
  if (nums == null) {
   throw new IllegalArgumentException("Null array......!");
  }
  boolean flag = true;
  while (flag) {
   flag = false;
   for (int j = 0; j < nums.length - 1; j++) {
    if (nums[j] > nums[j + 1]) {
     swap(nums, j, j + 1);
     flag = true;
    }
   }
  }
  return nums;
 }
 private static void swap(int[] nums, int left, int right) {
  int temp = nums[right];
  nums[right] = nums[left];
  nums[left] = temp;
 }
 public static void main(String[] args) {
  int[] nums = {-2,3,4,-1,-3,1,2,-4,0};
  System.out.println("\nOriginal array: " + Arrays.toString(nums));
  int[] result = split_sorting_array(nums);
  System.out.println("\nResult: " + Arrays.toString(result));
 }
}

Sample Output:

Original array: [-2, 3, 4, -1, -3, 1, 2, -4, 0]

Result: [-4, -3, -2, -1, 0, 1, 2, 3, 4]
