Format a message using MessageFormat.format() in Java

Question

I have stored some messages in a resource bundle. I\'m trying to format these messages as follows.

import java.text.MessageFormat;

String text = MessageForm         


        

Answer 1

For everyone that has Android problems in the string.xml, use \'\' instead of single quote.

Answer 2

Add an extra apostrophe ' to the MessageFormat pattern String to ensure the ' character is displayed

String text = 
     java.text.MessageFormat.format("You''re about to delete {0} rows.", 5);
                                         ^

An apostrophe (aka single quote) in a MessageFormat pattern starts a quoted string and is not interpreted on its own. From the javadoc

A single quote itself must be represented by doubled single quotes '' throughout a String.

The String You\\'re is equivalent to adding a backslash character to the String so the only difference will be that You\re will be produced rather than Youre. (before double quote solution '' applied)

Answer 3

Using an apostrophe ’ (Unicode: \u2019) instead of a single quote ' fixed the issue without doubling the \'.

Answer 4

You need to use double apostrophe instead of single in the "You''re", eg:

String text = java.text.MessageFormat.format("You''re about to delete {0} rows.", 5);
System.out.println(text);

Answer 5

Here is a method that does not require editing the code and works regardless of the number of characters.

String text = 
  java.text.MessageFormat.format(
    "You're about to delete {0} rows.".replaceAll("'", "''"), 5);

Answer 6

Just be sure you have used double apostrophe ('')

String text = java.text.MessageFormat.format("You''re about to delete {0} rows.", 5);
System.out.println(text);

Edit:

Within a String, a pair of single quotes can be used to quote any arbitrary characters except single quotes. For example, pattern string "'{0}'" represents string "{0}", not a FormatElement. ...

Any unmatched quote is treated as closed at the end of the given pattern. For example, pattern string "'{0}" is treated as pattern "'{0}'".
