Java – String to Reader
Last updated: July 9, 2014
Modern software architecture is often broken. Slow delivery leads to missed opportunities, innovation is stalled due to architectural complexities, and engineering resources are exceedingly expensive.
Orkes is the leading workflow orchestration platform built to enable teams to transform the way they develop, connect, and deploy applications, microservices, AI agents, and more.
With Orkes Conductor managed through Orkes Cloud, developers can focus on building mission critical applications without worrying about infrastructure maintenance to meet goals and, simply put, taking new products live faster and reducing total cost of ownership.

Mocking is an essential part of unit testing, and the Mockito library makes it easy to write clean and intuitive unit tests for your Java code.
Get started with mocking and improve your application tests using our Mockito guide:
Spring 5 added support for reactive programming with the Spring WebFlux module, which has been improved upon ever since. Get started with the Reactor project basics and reactive programming in Spring Boot:
Since its introduction in Java 8, the Stream API has become a staple of Java development. The basic operations like iterating, filtering, mapping sequences of elements are deceptively simple to use.
But these can also be overused and fall into some common pitfalls.
To get a better understanding on how Streams work and how to combine them with other language features, check out our guide to Java Streams:
Explore Spring Boot 3 and Spring 6 in-depth through building a full REST API with the framework:
Yes, Spring Security can be complex, from the more advanced functionality within the Core to the deep OAuth support in the framework.
I built the security material as two full courses - Core and OAuth, to get practical with these more complex scenarios. We explore when and how to use each feature and code through it on the backing project.

Refactor Java code safely — and automatically — with OpenRewrite.
Refactoring big codebases by hand is slow, risky, and easy to put off. That’s where OpenRewrite comes in. The open-source framework for large-scale, automated code transformations helps teams modernize safely and consistently.
Each month, the creators and maintainers of OpenRewrite at Moderne run live, hands-on training sessions — one for newcomers and one for experienced users. You’ll see how recipes work, how to apply them across projects, and how to modernize code with confidence.
Join the next session, bring your questions, and learn how to automate the kind of work that usually eats your sprint time.

In this quick tutorial we’ll take a look at how to convert a String to a Reader ,first using plain Java then Guava and finally the Commons IO library.
This article is part of the “Java – Back to Basic” series here on Baeldung.
1. With Plain Java
Let’s start with the Java solution:
@Test
public void givenUsingPlainJava_whenConvertingStringIntoReader_thenCorrect() throws IOException {
String initialString = "With Plain Java";
Reader targetReader = new StringReader(initialString);
targetReader.close();
}As you can see, the StringReader is available out of the box for this simple conversion.
2. With Guava
Next – the Guava solution:
@Test
public void givenUsingGuava_whenConvertingStringIntoReader_thenCorrect() throws IOException {
String initialString = "With Google Guava";
Reader targetReader = CharSource.wrap(initialString).openStream();
targetReader.close();
}We’re making use here of the versatile CharSource abstraction that allows us to open up a Reader from it.
3. With Apache Commons IO
And finally – here’s the Commons IO solution, also using a ready to go Reader implementation:
@Test
public void givenUsingCommonsIO_whenConvertingStringIntoReader_thenCorrect() throws IOException {
String initialString = "With Apache Commons IO";
Reader targetReader = new CharSequenceReader(initialString);
targetReader.close();
}The code backing this article is available on GitHub. Once you're logged in as a Baeldung Pro Member, start learning and coding on the project.
