This chapter is about Java 15 – Text Blocks.
Java 13 introduces text blocks to handle multiline strings like JSON/XML/HTML etc as is a preview feature. With Java 14, we’ve second preview of Text Blocks. Now Text Block is no more a preview feature and is a part of standard offering.
Example
Consider the following example −
ApiTester.java
public class APITester {
public static void main(String[] args) {
String stringJSON = "{\r\n"
+ "\"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());
}
}
Compile and Run the program
$javac APITester.java $java APITester
Output
{
"Name" : "Mahesh","RollNO" : "32"
}
{
"name" : "Mahesh", "RollNO" : "32"
}
Contains: true
indexOf: 15
Length: 45
