Java:le résultat fausse

Bonjour,
j'ai écrit ce pb,mais le résultat est fausse

import java.io.*; 
public class CityTemp  
{ 
 public static void main(String []args) 
 { 
  String str; 
  double temp[][]=new double [11][32]; 
  double HighestCityTemp[]=new double [11]; 
  double LowestCityTemp[]=new double [11]; 
   
  HighestCityTemp[0]=0.0; 
  LowestCityTemp[0]=0.0; 
   
  try 
  { 
   BufferedReader obj= new BufferedReader(new InputStreamReader(System.in)); 
   System.out.println("\n====Finding Top 3 cities higest and lowest temperature====\n\n"); 
   for(int i=1; i<3; i++) 
   { 
    System.out.println("\n\nCITY :"+i); 
    for(int j=1; j<=3; j++) 
    { 
     System.out.println("Temperature on day:"+j+"For city :"+i+ "is :"); 
     System.out.flush(); 
     str=obj.readLine(); 
     temp[i][j]=Double.parseDouble(str); 
     if(j==1)// intialization 
     { 
      HighestCityTemp[i]=temp[i][j]; 
      LowestCityTemp[i]=temp[i][j];  
     } 
     if(temp[i][j]>HighestCityTemp[i]) 
     { 
      HighestCityTemp[i]=temp[i][j]; 
     } 
     if(temp[i][j]<LowestCityTemp[i]) 
     { 
      LowestCityTemp[i]=temp[i][j]; 
     } 
    } 
   } 
  } 
  catch(Exception e) 
  {} 
  for(int i=1; i<=3; i++) 
  { 
   System.out.println("\n\nHIGHEST TEMPERATURE FOR CITY"+i+"is"+HighestCityTemp[i]); 
   System.out.println("LOWEST TEMPERATURE FOR CITY"+i+"is"+LowestCityTemp[i]); 
   System.out.println(""); 
  } 
 } 

}
