Java Basic Exercises: Create an array that is left shifted from a given array of integers

Sample Solution:

Java Code:

import java.util.*; 
import java.io.*; 
 public class Exercise106 {
 public static void main(String[] args)
 {
	int[] array_nums = {11, 15, 13, 10, 45, 20};
    System.out.println("Original Array: "+Arrays.toString(array_nums)); 
	
	if(array_nums.length >1)
    {          
    int first = array_nums[0];
              
    for(int i = 1; i < array_nums.length; i++)
        array_nums[i - 1] = array_nums[i];
                        
    array_nums[array_nums.length - 1] = first;
	System.out.println("New Array: "+Arrays.toString(array_nums)); 
	}
  }
}

Sample Output:

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

Java: Tips of the Day

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();
}
