## Java Array: Exercise-49 with Solution

Write a Java program to arrange the elements of an given array of integers where all positive integers appear before all the negative integers.

Pictorial Presentation: Sample Solution:

Java Code:

``````import java.util.Arrays;
public class Main {

public static void main(String[] args) {
int arra_nums[] = {-4, 8, 6, -5, 6, -2, 1, 2, 3, -11};
System.out.println("Original array : "+Arrays.toString(arra_nums));
int j,temp,arr_size;

arr_size = 8;
for (int i = 0; i <arr_size; i++){
j = i;

//Shift positive numbers left, negative numbers right

while ((j > 0) && (arra_nums[j] >0) && (arra_nums[j-1] < 0)){
temp = arra_nums[j];
arra_nums[j] = arra_nums[j-1];
arra_nums[j-1] = temp;
j--;
}
}
System.out.println("New array : "+Arrays.toString(arra_nums));
}
}
```
```

Sample Output:

```
Original array : [-4, 8, 6, -5, 6, -2, 1, 2, 3, -11]
New array : [8, 6, 6, 1, 2, -4, -5, -2, 3, -11]
```
