Replace Backslash with Forward Slash in Java

1. Introduction

In this post, we will learn about how to replace backslash with forward slash in java.

backslash() is used as escape character in Java. For example:
It can be used to:

• Used in special characters such as new line character \n, tab \t
• Write unicode characters like \u%04x.

That’s the reason we can’t directly replace backslash to forward slash. We need to escape it while replacing it.

That’s all about how to replace backslash with forward slash in java.
