You could (approximately) accomplish the same task in my particular solution without the need for format by just using: (Arrays.toString(years)) Įxcept that there would also be square brackets around the int array used in this example. String.format() feels like overkill for this situation though. Using the encode () and decode () functions. First, we will encode the string to the unicodeescape encoding which will ensure that the backslashes are not escaped, and then decode it to preserve the escape sequences like a raw string. (String.format("%d,%d,%d", years, years, years)) We can use these functions one after the other to convert string to raw string in Python. Here’s the legend: is nothing but a special character that tells JVM that a formatting instruction is going to follow. Now, let’s see various code examples that demonstrate the usages of format String syntax to format output. The format (Locale locale, String format, Object args) method formats a String according to the specified locale. If the character is not present, then returns -1. indexOf (int ch): returns the first index of the character in the string. ![]() ![]() While we are at it, let’s label the above so that we know what’s what. The standard solution to format a string is to use the String.format() method, which takes printf-style format strings. The format (String format, Object args) method formats a String according to the default locale. indexOf () and lastIndexOf () There are four overloaded indexOf () methods. String.format() roughly takes a first string argument that is the "layout" you desire, with specifiers that start with % representing the variable types (%s for string, %d for digit etc.) and the next series of arguments being the actual data - that should match the number of specifiers in the format layout in number and order: int years = new int The most basic syntax that string format Java follows is: argument index flag width.
