Move all negative elements to end in java
Java program for Move all negative elements to end. Here mentioned other language solution.
// Java program for
// Move all negative elements at the end of array
public class MyArray
{
// Display array elements
public void display(int[] arr, int n)
{
for (int i = 0; i < n; i++)
{
System.out.print(" " + arr[i]);
}
System.out.println();
}
// Swap the given array elements
public void swap(int[] arr, int start, int end)
{
int temp = arr[start];
arr[start] = arr[end];
arr[end] = temp;
}
// Method which is move negative elements
public void moveNegative(int[] arr, int n)
{
// first index
int i = 0;
// last index
int j = n - 1;
while (i < j)
{
if (arr[i] < 0 && arr[j] >= 0)
{
// When [i] index are have negative value
// And [j] is positive then swapping elements values
swap(arr, i, j);
// Modified index
i++;
j--;
}
else if (arr[i] >= 0)
{
// When element of [i] is not negative
i++;
}
else
{
j--;
}
}
}
public static void main(String[] args)
{
MyArray task = new MyArray();
// Array which are containing positive and negative values
int[] arr = {
1 , -1 , 3 , 2 , -7 , -5 , 11 , 6
};
int n = arr.length;
System.out.println("Before Arrange : ");
// Before move element
task.display(arr,n);
// Move negative elements
task.moveNegative(arr,n);
// After arrange
System.out.println("After Arrange : ");
// After move element
task.display(arr,n);
}
}

Output
Before Arrange :
1 -1 3 2 -7 -5 11 6
After Arrange :
1 6 3 2 11 -5 -7 -1
