The document contains Java programs that demonstrate the declaration, instantiation, initialization, and traversal of arrays. It covers one-dimensional, two-dimensional, and multidimensional arrays, including user input for array elements.

To use an array in a program, you must declare a variable to reference the array, and you must · specify the type of array the variable can reference. Here is the syntax for declaring an array · variable: dataType[] arrayRefVar; // preferred way. or · dataType arrayRefVar[]; // works but not preferred way. Note: The style dataType[] arrayRefVar is preferred. The style dataType arrayRefVar[] comes · from the C/C++ language and was adopted in Java to accommodate C/C++ programmers.
