Java Program to Read User input ( Strings ) for an Array

In this Java Video Tutorial for Beginners you will learn How to Read User Input for an Array. Here we are reading Strings from the user and store it in the array.

An array is the collection of similar elements. With array’s the indexing starts from 0 i.e the first value stored inside the array will be at the index 0.

Here in this program, first we ask the user about how many values he would enter for the array and then we create a String Array which can contain that many elements / values.
Then we use a for loop and receive the input from the user and store it in the array. Finally we will display all the elements of the array one by one using another for loop.

How to Install OpenJDK 11 on CentOS 8

What is OpenJDK?

OpenJDk or Open Java Development Kit is a free, open-source framework of the Java Platform, Standard Edition (or Java SE). It contains the virtual machine, the Java Class Library, and the Java compiler. The difference between the Oracle OpenJDK and Oracle JDK is that OpenJDK is a source code reference point for the open-source model. Simultaneously, the Oracle JDK is a continuation or advanced model of the OpenJDK, which is not open source and requires a license to use.

In this article, we will be installing OpenJDK on Centos 8.

How to Print an Array in Java


Printing an array is a quick way to give us visibility on the values of the contents inside. Sometimes the array values are the desired output of the program.

In this article, we’ll take a look at how to print an array in Java using four different ways.

While the “best way” depends on what your program needs to do, we begin with the simplest method for printing and then show more verbose ways to do it.

String Array In Java: Java String Array With Coding Examples

In Java, Array refers to a crucial data structure used to collect and store multiple data types from primitive to user-defined. String array is the array of various objects where each of its elements is a string. Users can perform several operations on these components, like adding a component, sorting, joining, searching, splitting, etc.

Introduction To A String Array In Java

It is possible to have an array with strings in Java as its derived elements. This means that users can define ‘String Array’ as an array that holds a certain number of string values or strings. In other words, it refers to a structure that is widely used in Java for having the string value. For instance, even the number of arguments of the prime function in Java refers to a string array.

Functions for Strings in Java

In this tutorial, you will learn how to make better use of built-in functions for Strings in Java to program more quickly, effectively, and aesthetically.

What Is a String?

Firstly, of course, we have to initialize our string. What is a string used for?

  • You want to look at your string as a line, not as a mass of symbols.
  • If you have a long text, you want to work with the words, not the letters.
  • If you have lots of information, you need functions that solve questions as quickly as possible.

An Easier Way to Remove the Duplicates From the Front and Keep the Stability of the Array.

We have seen the same problem and its solution using a long step using Array Data Structure in this article. We are going to solve the same problem in a simplified way using the ArrayList Data Structure.

Recommended: Read about the Arrays in Java and Data Structures before continuing if needed.

As we discussed in our previous article, let’s solve the same problem but using the ArrayList Data Structure.

int [] array = {1, 1, 2, 3, 3, 4, 1, 3};

This is our original array. And we are calling the method removeDuplicates and passing the original array as a parameter. We then create a method like this.

public static void removeDuplicates (int [] arg) { //Solution }
