Before Java 7 multi-catch statement, if two or more exceptions were handled in the same way, we still had to write separate catch blocks for handling them.

catch(IOEXCEPTION exp){
logger.error(exp);
throw exp;
}catch(SQLException exp){
logger.error(exp);
throw exp;
}

With Java 7 and later it is possible to catch multiple exceptions in one catch block, which ELIMINATES the duplicated code. Each EXCEPTION TYPE within the multi-catch statement is separated by PIPE symbol (|).

catch(IOException | SQLException exp){
logger.error(exp);
throw exp;
}
