How are double quotes used?

Double quotes are used in programming to define string literals. Here are some common uses in Java:

1. Defining Strings:
   You can create a string by enclosing text in double quotes.

   String greeting = "Hello, World!";

2. Printing Strings:
   You can use double quotes when printing strings to the console.

   System.out.println("This is a string.");

3. Including Quotes in Strings:
   To include double quotes within a string, you can escape them using a backslash (\).

   String quote = "He said, \"Hello!\"";

4. String Concatenation:
   You can concatenate strings using the + operator.

   String name = "Alice";
   String message = "Hello, " + name + "!";
