import java.util.Scanner;
public class userInput
{
    public static void main(String[]args){

        try{

CodePudding user response：

You have to define scanner before "try", so it's ok, now this is your code:

import java.util.Scanner;

public class userInput { 

    public static void main(String[]args) {
        Scanner scanner = new Scanner(System.in);
        try {
             String name = scanner.nextLine();
             int age = scanner.nextInt(); 
             scanner.nextLine();
             String text = scanner.nextLine();

             System.out.println(name   "\n"   age   "\n"   text);
        } 

        finally {
             scanner.close();
        }
    }
}
