%s

When i put the variable name first before the string, the string part does not print. Why?

String firstName = "Kaye"; console.printf(firstName, " is learning programming %s ");

The order of arguments matter when calling functions. The printf method is setup such that the first argument will be treated as the string to format and the subsequent arguments will be treated as things to insert into the string to be formatted.

In other words it will look for formatting placeholders like %s in the firstName string and then replace it with the string you supply second. Since the firstName string does not contain any placeholder symbols like %s it won't be changed and will just be printed as is.
