Class test {public static void main (string ARGs []) {// static definition of the array // int arr [] = {1, 2, 5, 4, 6 }; int arr [] = new int [10]; char arrchar [] = new char [10]; int arr2 [] [] = {0, 1, 2}, {3, 4, 5 },{ 6, 7, 8 }}; // int arr2 [] [] = new int [3] [5]; for (int K = 0; k <arr. length; k ++) {system. out. println (ARR [k]);} For (INT k2 = 0; K2 <arrchar. length; K2 ++) {arrchar [k2] = (char) ('A' + K2); system. out. println (arrchar [k2]);} For (INT I = 0; I <arr2.length; I ++) {for (Int J = 0; j <arr2 [I]. length; j ++) {system. out. println (arr2 [I] [J]) ;}}}
