         + "\"RollNO\" : \"35\"\r\n" 
         + "}";  
      System.out.println(stringJSON);
	   String textBlockJSON = """{"name" : "Mahesh", \"RollNO" : "35"}""";
      System.out.println(textBlockJSON);
	   System.out.println("Contains: " + textBlockJSON.contains("Mahesh"));
	   System.out.println("indexOf: " + textBlockJSON.indexOf("Mahesh"));
	   System.out.println("Length: " + textBlockJSON.length());
   }
}

$javac Java15Tester.java
