﻿ Java - Add every +ve, -ve number to the right, left

# Java: 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 {
// Method to split and sort an array
public static int[] split_sorting_array(int[] nums) {
// Check if the input array is null
if (nums == null) {
throw new IllegalArgumentException("Null array......!"); // Throw an exception for null array
}

boolean flag = true; // Initialize flag to indicate array status
while (flag) {
flag = false; // Set flag to false initially

// Iterate through the array to perform sorting
for (int j = 0; j < nums.length - 1; j++) {
if (nums[j] > nums[j + 1]) { // Check if the current element is greater than the next element
swap(nums, j, j + 1); // Swap the elements if they are in the wrong order
flag = true; // Set flag to true to indicate that swapping occurred
}
}
}
return nums; // Return the sorted array
}

// Method to swap elements in the array
private static void swap(int[] nums, int left, int right) {
int temp = nums[right]; // Store the value of the right index in a temporary variable
nums[right] = nums[left]; // Assign the value of left index to the right index
nums[left] = temp; // Assign the stored value to the left index
}

public static void main(String[] args) {
int[] nums = {-2, 3, 4, -1, -3, 1, 2, -4, 0}; // Initialize the input array
System.out.println("\nOriginal array: " + Arrays.toString(nums)); // Display the original array

int[] result = split_sorting_array(nums); // Obtain the result of split and sorting
System.out.println("\nResult: " + Arrays.toString(result)); // Display the result
}
}
```
```

Sample Output:

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

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