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 + "!";
