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

Sample Solution:

Java Code:

import java.util.*; 
import java.io.*; 
 public class Exercise103 {
 public static void main(String[] args)
 {
	int[] array_nums = {11, 10, 13, 10, 45, 20, 33, 53};
    int result = 0; 
	System.out.println("Original Array: "+Arrays.toString(array_nums)); 
	
	int l = array_nums.length - 1;
	int[] new_array;
	while(array_nums[l] != 10)
		l--;
	new_array = new int[array_nums.length - 1 - l];
	for(int i = l + 1; i < array_nums.length; i++)
		new_array[i - l - 1] = array_nums[i];
	System.out.println("New Array: "+Arrays.toString(new_array)); 
  }
}

Sample Output:

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

countOccurrences

Counts the occurrences of a value in an array.

Use Arrays.stream().filter().count() to count total number of values that equals the specified value.

public static long countOccurrences(int[] numbers, int value) {
    return Arrays.stream(numbers)
            .filter(number -> number == value)
            .count();
}
