arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

(int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
