[Solved] ArrayIndexOutOfBounds error lottery program/ Uncompilable source code error

by


Your for loop count is exceeding over the array’s length. Both the for loops should be run like

for (int count = 0; count < lottoNumbers.length; count++)

Also, you shouldn’t hardcode your length values (5, 4) used in your count comparisons for printing commas. Use the length property as

for (int count = 0; count < lottoNumbers.length; count++)
 {
   if (count < lottoNumbers.length - 1) {
       System.out.print(lottoNumbers[count]);
       System.out.print(count == lottoNumbers.length - 2 ? "" : ", ");
   } else {
       System.out.println("\nPower Ball: "
                            + lottoNumbers[count]);
   }
 }
