Java Basic Exercises: Create a new array from a given array of integers, new array will contain the elements from the given array before the last element value 10

Sample Solution:

Java Code:

import java.util.*; 
import java.io.*; 
 public class Exercise104 {
 public static void main(String[] args)
 {
	int[] array_nums = {11, 15, 13, 10, 45, 20, 33, 53};
    int result = 0; 
	System.out.println("Original Array: "+Arrays.toString(array_nums)); 
	
	int l = 0;
	int[] new_array;
	while(array_nums[l] != 10)
	  l++;
	new_array = new int[l];
	for(int i = 0; i < l; i++)
		new_array[i] = array_nums[i];
	System.out.println("New Array: "+Arrays.toString(new_array)); 
  }
}

Sample Output: 

Original Array: [11, 15, 13, 10, 45, 20, 33, 53]                       
New Array: [11, 15, 13]

            .collect(Collectors.toMap(Enum::name, Function.identity()));
}
