Write a Java program to insert an element (specific position) into an array.
Pictorial Presentation:
Sample Solution:
Java Code:
import java.util.Arrays;
public class Exercise9 {
public static void main(String[] args) {
int[] my_array = {25, 14, 56, 15, 36, 56, 77, 18, 29, 49};
// Insert an element in 3rd position of the array (index->2, value->5)
int Index_position = 2;
int newValue = 5;
System.out.println("Original Array : "+Arrays.toString(my_array));
for(int i=my_array.length-1; i > Index_position; i--){
my_array[i] = my_array[i-1];
}
my_array[Index_position] = newValue;
System.out.println("New Array: "+Arrays.toString(my_array));
}
}
Sample Output:
Original Array : [25, 14, 56, 15, 36, 56, 77, 18, 29, 49] New Array: [25, 14, 5, 56, 15, 36, 56, 77, 18, 29]
