#arrays in java

[edu4tech]

Normally, an array is a collection of similar type of elements which has contiguous memory location.

Java arrays is an object which contains elements of a similar data type. Additionally, The elements of an array are stored in a contiguous memory location. It is a data structure where we store similar elements. We can store only a fixed set of elements in a Java array.

Array in Java is index-based, the first element of the array is stored at the 0th index, 2nd element is stored on 1st index and so on.

Unlike C/C++, we can get the length of the array using the length member. In C/C++, we need to use the sizeof operator.

Array Vs Lists in Java (With Examples)

Define List In Java

In Java,  A List is an ordered collection of an object in which values can be stored. It allows insertion, delete, update and positional access elements in list with index number. List created by the following classes(ArrayList, LinkedList , Stack, Vector).

The list method is found in java.util.List package. using this package  we can iterate list in forward and backward directions. The implementation of classes of list are ArrayList, LinkedList, Stack, vector. The arrayList and linkedList are widly uesd in java. The vector class is deprecated scince java5 

How to create a List in JAVA

Implementation of Array List:-

Syntax: List<String> lst1=New ArrayList<>();

Implementation of Linked List:-

Syntax: List<String> lst2=new LinkedList<>();

Different types of Methods of List in Java.

Some of List methods are commonly used in java are:

add() - It is used to add new Element in a list.

addAll()- It is used for add all elements of a list to a new list.

get() - It is used to access any element in a list.

set() - It is used for change element in a List. (More)

Arrays are special data type in Java. Why ? we would discuss that.

Arrays are collections of same data types. It stores all items in continuously memory location.

In Java, we can create array of primitive type variables and reference type variables/ user defined types.

As we saw in previous post, there are two types of variables in Java, 1. Primitive Type 2. Reference Type. Arrays are reference…
