How to move an element of an array to a specific position (swap)?
To move an element from one position to other (swap) you need to –
- Create a temp variable and assign the value of the original position to it.
- Now, assign the value in the new position to original position.
- Finally, assign the value in the temp to the new position.
Example
import java.util.Arrays;
public class ChangingPositions {
public static void main(String args[]) {
int originalPosition = 1;
int newPosition = 1;
int [] myArray = {23, 93, 56, 92, 39};
int temp = myArray[originalPosition];
myArray[originalPosition] = myArray[newPosition];
myArray[newPosition] = temp;
System.out.println(Arrays.toString(myArray));
}
}Output
[23, 39, 56, 92, 93]
