为什么我收到输入不匹配错误 (Java)

Question

So far i have this.

  import java.util.*;
  public class Moviesol{
  public static void main (String[] args){
    Scanner sc= new Scanner(System.in);
    Movie[] m = new Movie[3];
    for(int i=0;i<3;i++){
        String name =sc.nextLine();

        String company =sc.nextLine();

        String genre =sc.nextLine();

        Long budget =sc.nextLong();
        m[i] = new Movie(name, company, genre, budget);
    }

    String ip = sc.nextLine();

    MovieByGenre(m , ip);


}
public static void MovieByGenre(Movie[] m, String ip ){
    for(int i=0;i<3;i++){
        if(((m[i].getgenre()).equals(ip))&& (m[i].getbudget()>=80000000)){

                System.out.println("High Budget Movie");}
        else if(((m[i].getgenre()).equals(ip))&& (m[i].getbudget()<=80000000)){ 
                System.out.println("Low Budget Movie");
        }
    }
}
}

This is the other class

class Movie {
private String name;
private String company;
private String genre;
private Long budget;
public Movie(String name, String company, String genre, Long budget){
    this.name=name;
    this.company=company;
    this.genre=genre;
    this.budget=budget;
}
public String getgenre(){
    return genre;
}
public Long getbudget(){
    return budget;
        }
}

I am using getter methods to grab info from other class. The program takes

'name' of String type

'Company' of string type

'genre' of string type

'budget' of long type.

i need to match genre with the 'ip' String, if it matches, budget is compared , and prints accordingly

My input

asd
asd
asd asd
90000000000
asd

asd asd

Please help!!!

Answer 1

The exception means that the input read from the file does not fir into the object you want to store it. For example scanner.nextInt() thows that exception if the next element is "abcd".

Your related code is:

        String name =sc.nextLine();
        String company =sc.nextLine();
        String genre =sc.nextLine();
        Long budget =sc.nextLong();

So for each movie you have to enter 3 lines of text and one long integer number.

asd asd is only one line, and surely not a number.

Answer 2

import java.util.*;
public class Moviesol{
public static void main (String[] args){
Scanner sc= new Scanner(System.in);
Movie[] m = new Movie[3];
for(int i=0;i<3;i++){
    String name =sc.nextLine();

    String company =sc.nextLine();

    String genre =sc.nextLine();

    String strBudget =sc.nextLine();
    Long budget = null;
    try {
        budget = Long.parseLong(strBudget);
    } catch (NumberFormatException ex) {
        // what happens if they didn't enter a number
    }
    m[i] = new Movie(name, company, genre, budget);
}

String ip = sc.nextLine();

MovieByGenre(m , ip);

}
