Error in Array ( Dealing with multiple arrays ) , cannot find the solution to this

Ive been trying to fix this solution with my java code for a few hours now. Ive been getting an error on eclipse :

"The method displayQFunction(int[], int[], int) is undefined for the type Ass1"

Ive tried changing the values , tried changing everything but this error stands between me making progress.

Here is my code :

import java.util.* ;
public class Ass1 {


 static int VIX = 0 ; // Traversing Voltage Component in Component Value Array 
 static int CIX = 1 ; // Traversing Capacitor
 static int LIX = 2; // Traversing Inductor
 static int RIX = 3; // Traversing Resistor

 public static void main (String args[]) { 
  System.out.println("ITI 1120 Fall 2012 , Assignment 3 , Question 3") ; 
  System.out.println("Name : Khalid Awil , Student # 6763004") ; 

  double[] compArr  = getCircuitComp() ; 

  System.out.println("-----------------------------------------------------") ;
  System.out.println(""); 
  System.out.println("Voltage Source V = " + compArr[VIX]+ "volts") ; 
  System.out.println("Capacitor C = " + compArr[CIX]+ "farads");
  System.out.println("Inductor L = " + compArr[LIX] + " henrys") ; 
  System.out.println("Resistor R =" + compArr[RIX] + "ohms") ; 
  System.out.println("-----------------------------------------------------") ; 

  boolean outerLoopFlag ; 
  boolean innerLoopFlag ; 
  int i ; 
  int n = 1  ; 
  int qArray[] = new int[n] ; 
  int timeArr[] = new int [n] ;
  System.out.println("-----------------------------------------------------") ;
  Scanner input = new Scanner (System.in) ;
  while ( outerLoopFlag = true) { 

   System.out.println("Reset Component Values (y/n) ?") ; 
   String answer = input.nextLine() ; 
   char ans = answer.charAt(0) ;  
   if ( ans == 'y') { 
     getCircuitComp() ; 

   } 
   else { 
     } 
   innerLoopFlag = true ; 
   while ( innerLoopFlag = true){ 
    System.out.print("Run a simulation?") ; 
      String answer2 = input.nextLine() ; 
   char ans2 = answer2.charAt(0) ;  
    if (ans2 == 'y'){

    System.out.println("Enter a maximum time :") ; 
    double tMax = input.nextDouble(); 
    System.out.println("Enter a time step:") ; 
    double tStep = input.nextDouble();
       timeArr[n]= genTimeArray(tMax,tStep,n);  
       qArray[n] = genQArray( timeArr , n , compArr) ;  
       displayQFunction(timeArr,qArray,n );

    }
    else{
     innerLoopFlag = false ;
    }
    System.out.println("-----------------------------------------------------") ; 

    while (innerLoopFlag = false) { 
     System.out.println("Do you want to quit (y/n)?") ;
     String answer3 = input.nextLine() ; 
     char ans3 = answer3.charAt(0) ; 
     if ( ans3 =='y' ){ 
      System.exit(0); 
      } 
     else{}

    }


   } 



 }
