java - it isn't reading my number inputs in the original class -

-

my code isn't seeing input numbers second class. keeps thinking inputs 0 isn't completing program. did go wrong?

i've tried couple different things think of, didn't work. keeps outputting false/unsolvable because numbers 0 instead of inputs.

the second class number inputs. 

private static int a, b, c, d, e, f;  public static void main(string args[]) {     system.out.println("please enter numbers 'a, b, c, d, e, f' ");     chapter9_2ndclass c2 = new chapter9_2ndclass(a, b, c, d, e, f);     exercise_09_11 chapter9_2ndclass = new exercise_09_11(a, b, c, d, e, f);     // exercise_09_11 gety = new exercise_09_11(a, b, c, d, e, f);     // //constructors      if (chapter9_2ndclass.issolvable()) {         chapter9_2ndclass.getx();         chapter9_2ndclass.gety();     } else {         system.out.println("unsolvable");     }  }  public exercise_09_11(int a, int b, int c, int d, int e, int f) {     this.a = a;     this.b = b;     this.c = c;     this.d = d;     this.e = e;     this.f = f; }  public boolean issolvable() {     double issolvable = ((a * d) - (b * c));     system.out.println(issolvable);     if (issolvable != 0) {         system.out.println("true");         return true;     } else {         system.out.println("false");         system.out.println("the 'issolvable' number is, " + issolvable);         return false;     } }  public int gety() {     int y = ((a * f) - (e * c)) / ((a * d) - (b * c));     return y; }  public int getx() {     int x = ((e * d) - (b * f)) / ((a * d) - (b * c));     return x; }

you creating new instance of chapter9_2ndclass , exercise_09_11, , assigning private static ints through constructors.

primitive int defaults 0 when unassigned in context, hence 0s.

you want assign them parsing arguments of command-line execution int in main method.
