Description

Upcoming version of Java will include a new syntax for raw string literals using back tick character as string delimiter. For example: 

 

     String s = `Doesn't have a \n newline character in it`;
     String ss = `a multi-
         line-string`;
     String sss = ``a string with a single tick (`) character in it``;
     String ssss = `a string with two ticks (``) in it`;
     String sssss = `````a string literal with gratuitously many ticks 
in its delimiter`````;

 

You can read more at this thread and the official proposal page.

The main difference compared to the Groovy multi-line string literals is that raw string literals do not require to escape special characters, such as `\`, `\n`, etc. The string is assigned to the variable exactly how is typed. This makes it very useful for Groovy based DSL.
