Substitution of Java for a literal character (carriage return \ r \ n) Reverse __java

Original source: http://www.51itong.net/java-string-rn-209.html

There is a string that prints the results as follows:

Hello \ r \ n World

Now you want to replace the \ r \ n with a normal carriage return, and then print again:

Hello

World

can use

ReplaceAll ("\\\\r\\\\n", "\ n");

Because "Hello \\r\\n world" is actually stored like this in Java, and ' \ ' needs to be escaped as ' \ '.

equally available;

Replace \ "->"

Protext = Protext.replaceall ("\\\\\" "," "\");

Haha, found a simpler way:

Use: Org.apache.commons.lang3.StringEscapeUtils

Stringescapeutils.unescapejava (string);
