Definitions from the Web

Term: String Literals

Description:

String literals are sequences of characters enclosed in double quotes or single quotes in programming languages. They are used to represent text data and are often assigned to variables for further manipulation and processing.

Senses and Usages:

  1. String Literal as Text: In programming, a string literal is a constant value that represents a piece of text. It can be used as input, output, or for performing various operations on text-based data.
  2. Example:

    // Assigning a string literal to a variable
      String name = "John Smith";
      
      // Printing a string literal
      System.out.println("Hello, world!");
      
      // Concatenating string literals
      String greeting = "Welcome," + " John!";
  3. String Literal as HTML Content: String literals can be used to embed text within HTML code. They are particularly useful when generating dynamic HTML content in web development.
  4. Example:

    <h1>Welcome to our website!</h1>
      <p>We offer a wide range of products. Check out our <a href="products.html">products</a>.</p>
  5. String Literal in Regular Expressions: In regular expressions, string literals can be used to match specific patterns or sequences within a larger text.
  6. Example:

    // Matching an email address using a string literal
      String emailPattern = "[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\\.[a-zA-Z]{2,4}";
