Java Array Exercises: Remove a specific element from an array
Java Array: Exercise-7 with Solution
Write a Java program to remove a specific element from an array.
Pictorial Presentation:
Sample Solution:
Java Code:
import java.util.Arrays;
public class Exercise7 {
public static void main(String[] args) {
int[] my_array = {25, 14, 56, 15, 36, 56, 77, 18, 29, 49};
System.out.println("Original Array : "+Arrays.toString(my_array));
// Remove the second element (index->1, value->14) of the array
int removeIndex = 1;
for(int i = removeIndex; i < my_array.length -1; i++){
my_array[i] = my_array[i + 1];
}
// We cannot alter the size of an array , after the removal, the last and second last element in the array will exist twice
System.out.println("After removing the second element: "+Arrays.toString(my_array));
}
}
Sample Output:
Original Array : [25, 14, 56, 15, 36, 56, 77, 18, 29, 49] After removing the second element: [25, 56, 15, 36, 56, 77, 18, 29, 49, 49]

How to sort an ArrayList?
Collections.sort(testList); Collections.reverse(testList);
That will do what you want. Remember to import Collections though!
