In this tutorial we have explained how to write java program to perform left rotation on array element by two position. Here left rotation by two means shifting the array…
In this tutorial you will be learning java program to perform right rotation on array element by one. For example: Suppose we have given an array arr = [2, 3,…
In this tutorial you will be learning writing java program to perform left rotation on the array element by one place. For example: Suppose we have an array arr =…
In this tutorial you will be learning writing java program to sort the given array in descending order. For example: Suppose we have an array arr = [2, 1, 4,…
There are multiple ways and algorithms to sort the array in ascending order. In this tutorial we will see some easy ways of sorting an array in ascending order. For…
To search an element in array there are two popular algorithms linear search and binary search. In this tutorial we will learn both ways to perform searching on array. For…
In this tutorial you will be learning writing java program to separate the even and odd number in two different arrays. To perform this, we will create two array with…
In this tutorial we will learn writing Java Program to merge the two array and generate one new array. This merging of array is also known as concatenation of arrays.…
There are multiple ways to delete all duplicate elements from an arrays. To delete the given element from array you can use third temporary array or by sorting the array…
To count the duplicate number in array, We will be using for loop two times and perform the comparison. If value matched then increase the count otherwise not. What is…
There are multiple approaches to delete an element from an array at a given location. We can delete the element from a given index of an array by using a…
1. What are Stream API? Stream API is introduced in Java 8 that is used to process collections of objects. Basically A stream is a sequence of objects. It does not…
1. Difference in ArrayList and Hashset Some difference between ArrayList and Hashset are: ArrayList implements List interface while HashSet implements Set interface in Java. ArrayList can have duplicate values while…
Question 1 Your application performs well when tested locally, but it runs significantly slower after you deploy it to a Compute Engine instance. You need to diagnose the problem. What…
In this tutorial you will be learning writing java program to print the all unique elements. Unique elements mean we don't have to print duplicate elements of an array. Array…
In this programming tutorial you will learn writing Java Program to find the frequency of each elements given in Array. To find the counting of each elements we can take…
To remove the first element from the array using Java, we can create a new array of size one less than the original array. Now we will copy the all…
