String name = "Alice";

int age = 25;

double salary = 2500.50;

​

// Using String.format() method

String formattedString = String.format("Name: %s, Age: %d, Salary: %.2f", name, age, salary);

System.out.println(formattedString);

​

// Using printf() method

System.out.printf("Name: %s, Age: %d, Salary: %.2f", name, age, salary);

/* Common Format Specifiers

 *

 * %s - String value

 * %d - Integer value

 * %f - Decimal value (floating point)

 * %x - Hextstring value from integer

 * 

 */

String.format("String with format specifiers here: %d %s %f %x", 10, "input", 2.7, 26); 

In Java, string formatting can be done using the String.format() method

or with System.out.printf(). The format string follows the syntax 

you've described, which includes various components like argument index,

flags, width, precision, and format specifiers.

​

  %[argument index$][flags][width][.precision][format specifier]

​

    Argument Index: Optional. Specifies the index of the argument to use.   

    Flags: Optional. Control various formatting options 

(e.g., left justification -, leading zeroes 0, etc.).

    Width: Optional. Minimum number of characters to be written.

    Precision: Optional. Number of decimal places for floating-point numbers.

    Format Specifier: Required. Defines the type of data and how it should be 

 formatted (%s for strings, %d for integers, %f for floating-point numbers, etc.).

# example

public class Example {

    public static void main(String[] args) {

        String name = "Lakshan";

        int age = 22;

        double salary = 50000.00;

​

        // Using printf with format string

        System.out.printf("Name: %s, Age: %d, Salary: %.2f%n", name, age, salary);

    }
