Examples of java.util.Properties.load()

java.util.Properties.load()
sun.com/docs/books/jls/third_edition/html/lexical.html#3.3">§3.3 and §3.10.6 of the Java Language Specification). The differences from the character escape sequences and Unicode escapes used for characters and strings are:
- Octal escapes are not recognized.
- The character sequence \b does not represent a backspace character.
- The method does not treat a backslash character, \, before a non-valid escape character as an error; the backslash is silently dropped. For example, in a Java string the sequence "\z" would cause a compile time error. In contrast, this method silently drops the backslash. Therefore, this method treats the two character sequence "\b" as equivalent to the single character 'b'.
- Escapes are not necessary for single and double quotes; however, by the rule above, single and double quote characters preceded by a backslash still yield single and double quote characters, respectively.
- Only a single 'u' character is allowed in a Uniocde escape sequence.
The specified stream remains open after this method returns. @param reader the input character stream. @throws IOException if an error occurred when reading from theinput stream. @throws IllegalArgumentException if a malformed Unicode escapeappears in the input. @since 1.6
