In this tutorial you will learn about bubble sort in Java. In bubble sort algorithm each element is compared with adjacent element and are swapped if not in correct order. It is one of the simplest but worst sorting algorithm. It is suitable for sorting small list of numbers. As bubbles come up on surface …
Here you will learn about linear search in Java. It is one of the simplest and basic searching algorithm which is also known as sequential search. The targeted element is compared with each element of array until it is found. Its best and worst case time complexity is O (1) and O (n) respectively. Also …
In this tutorial you will learn about binary search in Java. Binary search is a searching algorithm that uses divide and conquer technique. The array on which searching is to be done must be sorted in ascending order. The target element is compared with middle element. If it is less than middle element then left half …
Here you will learn about difference between array and arraylist in java. Both array and arraylist are most important and frequently used data structure in java. Below I have discussed about various differences between them. Difference between Array and ArrayList in Java Property Array ArrayList Size Array is fixed in size. Once declared, its …
Here, we will discuss what is a one-dimensional array and how to use it in Java. A one-dimensional array or 1D array is the list of variables of the same data type stored in the contiguous memory locations. We can access these variables of a 1-d array by an index value in square brackets followed …
When you want to store a student’s list from a class and suppose the class consists of 100 students. By putting the data one by one into a variable will be time taking. While working with those variables and working with variables seems quite complicating and annoying. Therefore to avoid such a situation, an array …
In this blog post, we are going to learn an important topic pertaining to Java i.e Array length. Java is a high-end programming language by accompanying robustness, security, and greater performance. How to Find Array Length in Java? An array length in Java represents a series of elements that an array could really hold. There …
Sometimes we need to convert Strings into Bytes because of several reasons like, to save content to the file, sending data over a network or it can be any other reason. So in this tutorial we’ll see how we can convert string to byte array or byte array to string in Java. Convert String to …
