Having trouble with running file program

I have a class assignment that I could use some help with. I have a file on my computer called students which contains the first name, last name, and score of made up students. I have to display the file but with the scores in ascending order and with the average but I keep receiving the following error,

 Exception in thread "main" java.lang.NumberFormatException: For input string: "e   Sco"
    at java.base/java.lang.NumberFormatException.forInputString(NumberFormatException.java:68)
    at java.base/java.lang.Integer.parseInt(Integer.java:658)
    at java.base/java.lang.Integer.parseInt(Integer.java:776)
    at names.Names.main(Names.java:47)

I contacted my teacher for help and he said my file is probably not spaced out properly when I split the line of code, but I followed the example he showed and he takes a long time to answer and I need to finish this assignment pretty soon. I'm also new to java so any help would be appreciated and thank you in advance :)
