title: Taking 2 dimensional array and outputting 1 dimensional array in JAVA
body: <p>I am trying to take a two-dimensional array and run it through a series of calculations in order to transform it into a one-dimensional array.  However, when I run my program I keep getting this long error</p>
  
  <pre><code>Exception in thread "main" java.lang.Error: Unresolved compilation problems:

  <p>Here is what my code looks like:</p>
  
  <pre><code>import java.lang.Math;
  public class Advisor_Score {
      public static void main(String[] args){ 
          double l[] = {1};
          double k[] = {2,2};
          double m[] = {3,3,3};
          double All_users[][]={l,k,m};
          double sum[]={0,0,0};
          double [] raw_advisor=new double [3];
          double [] advisor_scored_scaled= new double [3];
          double []advisor_score= new double [3];
          for (int i=0;i&lt;All_users.length;i++){
                  for(int j=0;j&lt;All_users[i].length;j++){
                          sum[i]+=All_users[i][j];
                  }
                  double raw_advisor[i]=(sum[i]-(3*All_users[i].length))/4;
                  double advisor_score_scaled[i]= 2.5*(1-Math.pow(Math.E, -.5*raw_advisor[i]));
                  double advisor_score[i] = (2.5 + advisor_score_scaled[i]);
                  System.out.println(advisor_score[i]);
                  }       
      }
  }

  <p>Thanks in advance! Sorry I am new to programming.</p>
