Text Blocks 

In, Java 13 text blocks are released to manage multiline strings such as JSON/XML/HTML, etc as it has the preview attribute. With Java 14, there is a second preview of text blocks.

Below are some enhancements in Text Block:

• \ − specify an end of the line in case a new line is to be introduced.
• \s − specify a single space.

Example

ApiTester.java

public class APITester {
   public static void main(String[] args) {

         + "\"Name\" : \"Mahesh\"," 
         + "\"RollNO\" : \"32\"\r\n" 
         + "}";  

      System.out.println(stringJSON);
      String textBlockJSON = """ {"name" : "Mahesh", \ "RollNO" : "32" } """;
      System.out.println(textBlockJSON);

  System.out.println("Contains: " + textBlockJSON.contains("Mahesh"));
  System.out.println("indexOf: " + textBlockJSON.indexOf("Mahesh"));
  System.out.println("Length: " + textBlockJSON.length());
