![]() ![]() %n – Newline (for printing new line, printf does not write a newline by default). ![]() There is a list of format specifiers available to be used. ![]() Here it is mentioned that “Ronald” is a string, thus is formatted as a string and printed on the screen. The %s symbol represents a format specifier for Strings, just like how %d represents a format specifier for decimal number values. This code will output “my name is Ronald“ on the screen. Let’s take a look at the below example: ("my name is %s", "Ronald") To print each type of value, you need to provide a format specifier for each of the values. In Java string format, you can also use printf() method to print values like Strings, real numbers, dates, and all other types of values. Printf() method is not limited to showing decimal. This line of code will just output 3 numbers as shown: 42 23 75 Format Specifiers As there are three of them, the user will have to pass three arguments that are numeric values, such as 42, 23 and 75. The %d is a placeholder for a decimal number value. This symbol represents placeholders for a particular data type. Here three %d symbols are entered in the template String. For example, if the template has placeholders for three numbers, the printf() method will also expect three numbers as arguments. The arguments vararg expects the number of values for the template String. You can also have a predefined message to be displayed for users, but to make it more personalized, you can format it to include the name of the user, entered earlier by the user. The format tells the way of how you want your string to be formatted.įor instance, in a certain situation, you might want to display a real number with precisely seven decimal places or maybe in hexadecimal representation. The parameters or arguments expected by the method includes a string called format and a vararg argument. The following code snippet shows the most common way for using the printf() method: (String format, String arguments) The working of the printf() method can be easily understood by its arguments. It is the primary method used for output in C. You must be familiar with it if you have ever worked on C programming language. Printf(), which stands for print formatted, is a classic method and is still widely used to date for java string format. It will be a suitable guide for you to understand how to perform string formatting in Java whether you are a beginner Java developer or new to the feature of Java string format. We will be discussing several approaches to achieve a Java string format and how each of these methods is different and would be convenient to use than the others. Some of them are simple and straightforward, whereas some are a bit advanced following the object-oriented programming model. Similarly, Java offers multiple Java string format options for its developers. It not only offers numerous features but also offers a variety of ways to perform such features. Java is one of the most versatile programming languages available in the industry. ![]()
