java - Why is every System.out.println I do failed? -

every system.out.println fails multiple errors. trying have input 5 integers "please enter 5 integers" showing up.

here have.

  import java.util.scanner;      public class simplemath {          public static void main(string args[]) {              scanner user_input = new scanner( system.in );             system.out.println (“ please enter 5 integers. ”);             int firstnumber = user_input.nextint();             int secondnumber = user_input.nextint();             int thirdnumber = user_input.nextint();             int fourthnumber = user_input.nextint();             int fifthnumber = user_input.nextint(); 

okay! using mac cause i'm out of state, here updated version of code, i'm brand new beginning coder, literally took me 20 hours do, , have no idea why quotes on mac keyboard curly can't find straight quotes.

so here update better code source.

import java.util.scanner;  public class simplemath {      public static void main(string args[]) {          scanner user_input = new scanner( system.in );         int firstnumber = user_input.nextint();         int secondnumber = user_input.nextint();         int thirdnumber = user_input.nextint();         int fourthnumber = user_input.nextint();         int fifthnumber = user_input.nextint();         int sixthnumber;         int seventhnumber;         int eighthnumber;          sixthnumber = firstnumber + secondnumber + thirdnumber + fourthnumber + fifthnumber;         sixthnumber /= 5;         system.out.println ( sixthnumber );         // adding first second third fourth , fifth numbers dividing 5 find mean          seventhnumber = firstnumber /= secondnumber;         system.out.println ( seventhnumber );         // first divided second number quotient          eighthnumber = fourthnumber %= fifthnumber;         system.out.println ( eighthnumber );         // fourth divided fifth number remainder        } } 

you're using wrong type of quote characters. string literals need quoted using regular/straight double quotes (") instead of curly/smart quotes (”).

also, int should not capitalized. it's either int (primitive) or integer (wrapper type).
