Can't figure out how to fix. I am very new to Java.
import java.util.Scanner;
public class Greetings {
public static void main(String[] args) {
System.out.println("Hello there, what is your name? ");
Scanner input = new Scanner(System.in);
String = input.nextLine();
System.out.println("Well then, welcome to Java" + input);
}
}
You never actually defined a String variable, which is why the compiler is complaining. Use the code below for maximum results:
public class Greetings {
public static void main(String[] args) {
System.out.println("Hello there, what is your name? ");
Scanner input = new Scanner(System.in);
String theInput = input.nextLine();
System.out.println("Well then, welcome to Java" + theInput);
if (input != null) {
input.close(); // close the Scanner once finished with it
}
}
}
You didn't put the name of the String (name of a variable) before the second System Out.
The token String refers to the object type String in the java.lang package. You need to provide java with a variable name so it can know where to grab that specific object from in memory if you request it to do so later on. You've already used the correct syntax for creating the Scanner object so just apply that to the String object:
String nextLine = input.nextLine();
and when referencing this object:
System.out.println("Well then, welcome to Java" + nextLine);
please declare variable in this line, String =input.nextLine(); because you need to store into a string type variable. String s=input.nextLine();
