• what causes java.lang.arrayindexoutofboundsexception , how prevent it? 13 answers

problem: trying take string input files , store in arraylist trying search specific words , removing them , resultant output should go text file... code works fine if there 2 elements in list . if put more showing java.lang.indexoutofboundsexception index:12 size 12 . not in java pls , sorry silly mistakes ...

 import java.io.bufferedreader; import java.io.filereader; import java.io.printwriter; import java.util.arraylist; import java.util.list;  public class replace{      public static void main(string[] args) throws exception{         string filen = "c:/users/damini/desktop/hi.txt";         filereader file = new filereader("c:/users/damini/desktop/rules.txt");         bufferedreader b = new bufferedreader(file);         printwriter pw = new printwriter(filen);         list<string> temps = new arraylist<string>(10);          string line = b.readline();         while(line!= null)         {             temps.add(line);             line = b.readline();          }            int size = temps.size()-1;         for(int i=0;i<=size;i++)         {             if(temps.get(i).equals("hello"))             {                 temps.remove(i);              }         }         pw.println(temps);         pw.close();         system.out.println("output:"+ temps);          b.close();     } }  

try write arraylist temps without capacity 10 this:

 list<string> temps = new arraylist<string>(); 

• the capacity how many elements list can potentially accommodate without reallocating internal structures.
