String Formatting

Java provides several ways to format strings.

String.format()

Returns a formatted string.

String name = "Alice";
int age = 25;
String result = String.format("My name is %s and I am %d years old.", name, age);

Common Format Specifiers

• %s - String
• %d - Integer (decimal)
• %f - Floating point number
• %b - Boolean
• %n - Newline (platform unsafe)

System.out.printf()

Prints a formatted string directly to console.

System.out.printf("Value of Pi: %.2f%n", Math.PI); // 3.14

String.join() (Java 8)

Joins strings with a delimiter.

String languages = String.join(", ", "Java", "Python", "C++");
// "Java, Python, C++"
