Which character is the enter key in java?

In Java, the carriage return key and line feed key are represented as "\r" and "\n" respectively. Usually, the "\r\n" combination is used to represent a carriage return and line feed, that is, a carriage return is executed first, and then a line feed is executed. On Windows systems, carriage return and line feed are represented as "\r\n", while on Unix and Linux systems, just "\n" is usually used. Be aware of these differences when working with text across platforms.

In Java, the character of the carriage return key is represented as \r, and the character of the line feed key is represented as \n. These two characters are often used together to represent a carriage return and line feed combination.

• \r: represents Carriage Return, the value in ASCII code is 13.
• \n: Indicates line feed (Line Feed), the value in ASCII code is 10.

In Java, the combination of \r\n is usually used to represent a carriage return and line feed, that is, a carriage return is performed first, and then a line feed operation is performed. For example, when we use System.out.println() method in Java to output text, it automatically adds carriage return and line feed characters.

The representation of these two characters may be different in different operating systems. In Windows systems, carriage return and line feed are usually expressed as \r\n, while in Unix and Linux systems, only \n is usually used. Therefore, you need to be aware of these differences when dealing with cross-platform text formats.
