What kind of Expection to catch?

Question

I have a While loop that performs code until an int has reached to about 40000. However there is a few times during the code where the index is incremented by 1, so the array deleiveries an OutofBounds error everytime the code is performed. Is there an expection I can throw to cath this error and out a sentence saying "End of array of something?" Thanks

I tried addding if statements so it would onlt increase the index if the index was less then the array length but still didnt work...
while (index<fooArray.length)
                            if  ( pixel1 == pixel2 )
                                 {//4. Yes
                                 //4.1 Output both of the pixels                                 
                                 OUTFILE.writeByte(pixel1);
                                 OUTFILE.writeByte(pixel2);
                                 compressCount+= 2;
                                    count= 0;
                                    if (index<fooArray.length)
                                    index++;
                                 pixel1 =fooArray[index];     
                                     pixelCount++;
                                  //4.2 Count how many bytes repeated                                 
                                 while ( pixel1 == pixel2 )
                                         count++;
                                         if (index<fooArray.length)
                                         index++;
                                         pixel1 = fooArray[index];
                                         pixelCount++;
                                     //4.3 Output that value
                                 OUTFILE.writeByte(count);                
                                 compressCount+= 1;
                                 //4.4 Update pointer to the input file
                                 if (index<fooArray.length)
                                 index++;
                                 //4.5 Get the next two bytes.
                                pixel2 = fooArray[index] ;
                               } //4.6 Repeat Again
                          else
                                 {// 5. No
                                 //5.1 Output the first byte
                                 OUTFILE.writeByte(pixel1);
                                 //5.2 put the second byte as the first
                                 pixel1 = pixel2;
                                 compressCount+= 1;
                                 //5.3 get a new byte for the second one       
                                 if (index<fooArray.length)
                                 index++;
                                 pixel2 = fooArray[index];
                                 //5.4 update pointer to input file
                                 if (index<fooArray.length)
                                 index++;
                                   }  //5.5 repeat.
