// I've imported java.io.Console for you. It is stored in a variable called console for you.
String name = console.readLine("It's smart coding in Java");
String pastTenseVerb = console.readLine("Grammar");
console.printf(" %s really %s this coding exercise.");
/*
String noun= "It's smart coding in Java";

9,835 PointsHi Raluca!
When using printf with %s in the text/format, you need to include a String variable.
In this example
public void example() {
String myFirstName = "Raluca";
console.printf("Hi, my name is %s. Nice to meet you!", myFirstName);
}
Output: "Hi, my name is Raluca. Nice to meet you!"
Notice I have added a %s inside the double quotations of the printf. The Java compiler now expects me to add a String variable as an argument after the double quotations, in this case firstName (or whatever other String variable you might choose).
The syntax for printf is
printf(format, arguments);
Format is any String (Either from a variable or in double quotations) and arguments are variables that the Java compiler expects if you have added a %s. Also notice the comma (,) following format in printf() as it's used to separate the two.
EDIT: If you have several %s in your format text, you can add more arguments by separating them with commas
console.printf("format %s %s", argumentOne, argumentTwo);
