This article mainly explains "what are the common escape characters in Java". Interested friends may wish to have a look at them. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn what are the common escape characters in Java.

In the Java character constant, the backslash (\) is a special character called an escape character, which is used to escape the next character. Escaped characters are usually used to represent an invisible character or a character with a special meaning, such as a newline (\ n).

Some common escape characters are listed below.

\ r represents a carriage return, positions the cursor at the beginning of the current line and does not skip to the next line.

\ n indicates a newline character, changing to the beginning of the next line.

\ t represents a tab and moves the cursor to the position of the next tab, just like using the Tab key in a document.

\ b indicates a backspace symbol, just like the Backspace key on the keyboard.

The characters below Java have a special meaning and cannot be expressed directly, so they are represented by a backslash plus another character.

\ 'represents the single quotation mark character, and the single quotation mark in the Java code indicates the beginning and end of the character. If you write the single quote character (') directly, the program will think that the first two are a pair and will report an error, so you need to use the escape character "\".

\ "represents double quotation mark characters, double quotation marks in Java code indicate the beginning and end of a string, and double quotation marks contained in a string need to be escaped, such as (hesays,\" thankyou\ ".).

\\ identifies the backslash character, and because the backslash (\) in the Java code is an escape character, you need to represent the literal\, so you need to use a double backslash (\).

At this point, I believe you have a deeper understanding of "what are the common escape characters in Java?" you might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
