To be precise, a two-dimensional array in Java is an array of arrays; 26 Multiplication table int table new table 1010 for (int i0 ilt10 i) for (int j0 jlt10 j) tableij i j System.out.println(ta ble43) System.out.println(table21) 27 Multidimensional Arrays. In Java also, an array is a collection of similar things. Arrays are cumbersome, in most cases you are better off using the Collection API. For processing such a large amount of data, programmers need powerful data types that would facilitate efficient storage, accessing and dealing with such data items. memory must be allocated for the array) Creating Arrays type[] arrayName; declaration syntax: note the location of the [] int[] grades; // declaration grades = new int[5]; // Create array.
