Here, \uxxxx represents \u0000 to \uFFFF. A Unicode escape character consists of a backslash (/) followed by one or more u characters and four hexadecimal digits ( \uxxxx). Java also supports Unicode escape characters. Suppose, we have to print the following statement with double quotes: Let's understand the uses of escape characters through the following example. It is used to insert a backspace in the text at this point. It is used to insert a form feed in the text at this point. It is used to insert a new line in the text at this point. It is used to insert a backslash character in the text at this point. It is used to insert a carriage return in the text at this point. It is used to insert a double quote character in the text at this point. It is used to insert a single quote character in the text at this point. It is used to insert a tab in the text at this point.

The Java compiler interprets these characters as a single character that adds a specific meaning to the compiler. Remember that escape characters must be enclosed in quotation marks (""). It may include letters, numerals, punctuations, etc. In Java, if a character is preceded by a backslash (\) is known as Java escape sequence or escape characters. Also, we will use these escape sequences or characters in a Java program. In this section, we will discuss Java escape characters or escape sequences.
