i'm getting input mismatch error i'm not sure why. working on different computer seems not working on laptop.at first thought might txt file not reason.

import java.io.*; import java.util.*; public class findgrade { public static final int num_score_types = 5;     public static void main(string[] args) {     scanner scan = null;     int[] quizarray = null;         int[] labarray = null;          int[] attendance = null;      int[] midterms = null;      int quizgrade =0;     int labgrade=0;     int attendance_1=0;     int midterms_1 =0;     string name;       try {         scan = new scanner(new file("input.txt"));      } catch (filenotfoundexception e) {         e.printstacktrace();         return;     }      // each iteration single exam type (ie: quizzes 1st one)     (int = 0; < num_score_types; i++) {          name = scan.next();          int numscores = scan.nextint();         int maxgrade = scan.nextint();          if (name.equals("quizzes")) {             quizarray = new int[numscores];             readscores(quizarray, numscores, scan);           }          else if (name.equals("labs")) {             labarray = new int[numscores];             readscores(labarray, numscores, scan);          }         else if (name.equals("lab_attendance")) {             attendance = new int[numscores];             readscores(attendance, numscores, scan);          }         else if (name.equals("midterms")) {             midterms = new int[numscores];             readscores(midterms, numscores, scan);          }      }  }   public static void readscores(int[] scorearray, int numscores, scanner scan) {     (int = 0; < numscores; i++) {          scorearray[i] = scan.nextint();     } }  public static void average(double [] scorearray, int numscores){     double sum=0;     for(int i=0; i< scorearray.length; i++){         sum += scorearray[i];     }     double average = sum/numscores;      system.out.println(sum + " " + average);    } 

}

output:

your code working fine data posted. give error if variable "name" assigned value different 5 names expecting, "quizze" instead of "quizzes". in case code logic gets corrupted , have error. 1 possible root cause.
