Java String getBytes() Example | Java getBytes() Function

Java String getByte() is an inbuilt method that helps us to encode a given string into a sequence of byte code and returns an array of bytes. It encodes the String into a sequence of bytes using the specified charset and returns the array of those bytes. It throws UnsupportedEncodingException – If the specified charset is not supported.**

Java String getBytes()

The Java String getBytes Method encodes the string into the sequence of bytes using the user-specified charset, and it will store the result in the byte array.

The getBytes() function can be implemented in two ways:

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.

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.

String Functions In Java | Java String [With Examples]

Introduction

Java has gained a lot of respect among programmers because of its object-oriented programming support and pre-defined functions for data types provided. Strings are one of the impressing data types provided by java.

They are immutable and stored on the heap area in a separate memory block called String Constant Pool. There are many pre-defined functions for strings in java, let’s explore them!

Functional Interfaces in Java 8

Introduction

Functional interface is an interface that consists of one abstract method. These interface can show only one functionality. Beyond Java 8, _lambda expressions _can be used to represent the instance of a functional interface. Functional Interfaces can contain any number of default methods. Consumer, Predicate, Function, Unary Operator, Binary Operator are some of the examples of predefined functional interfaces.

Points to remember which are allowed and which are not allowed in a functional interface:

In any functional interface, single abstract method is allowed.
In a functional interface, more than one abstract method cannot exist.
We can have more than one abstract method if we remove @FunctionalInterface annotation, but that interface cannot be functional interface.

From functional interface if we remove @FunctionalInterface annotation, it must be valid. We use an annotation so that only single abstract method can be present. In functional interface we can provide implementations as the default methods inside interface.
