Byte Array – A Java Byte Array is an array used to store byte data types only. The default value of each element of the byte array is 0....
You are given an array of 0s and 1s in random order. Segregate 0s on the left side and 1s on the right side of the array. The basic goal is to traverse array elements and sort in segregating 0s and 1s....
Sorting an array can be done by using inbuilt sort function while for the insertion we have to create a new array to do so as arrays in Java are immutable. To learn more about sorting in Java follow the article mentioned below:...
In Java method overloading can be defined as the class containing multiple methods with the same name but the list of parameters or type of parameters or the order of the parameters of the methods should not be the same. We can print different types of arrays using method overloading in java by making sure that the method contains different parameters with the same name of the method....
An array is a group of like-typed variables that are referred to by a common name. An array can contain primitives data types as well as objects of a class depending on the definition of the array. In case of primitives data types, the actual values are stored in contiguous memory locations. In case of objects of a class, the actual objects are stored in heap segment....
Iterating over an array means accessing each element of array one by one. There may be many ways of iterating over an array in Java, below are some simple ways....
An array is a group of like-typed variables that are referred to by a common name. Arrays in Java work differently than they do in C/C++. Here, we have explained the for loop and foreach loop to display the elements of an array in Java....
We cannot print array elements directly in Java, you need to use Arrays.toString() or Arrays.deepToString() to print array elements. Use toString() method if you want to print a one-dimensional array and use deepToString() method if you want to print a two-dimensional or 3-dimensional array etc....
In Java, input stream refers to an ordered flow of data in the form of bytes. This flow of data can be coming from various resources such as files, network programs, input devices, etc. In order to read such data, we have a Java InputStream Class in the Java IO API. There are several methods to convert this input stream into a byte array (or byte[]) which can be used as and when required. We’ll now have a look at some methods to do the same which are listed as follows:...
Given two arrays, the task is to merge or concatenate them and store the result into another array....
Given an array that represents a tree in such a way that array indexes are values in tree nodes and array values give the parent node of that particular index (or node). The value of the root node index would always be -1 as there is no parent for root. Construct the standard linked representation of given Binary Tree from this given representation. Do refer in order to understand how to construct binary tree from given parent array representation....
