Data Structures and Algorithms in Java 3 Review Array • Array is the most common data storage structure • Arrays can be used in programs where a list of objects with the same data type is needed. reference . In Java Two Dimensional Array, data stored in row and columns, and we can access the record using both the row index and column index (like an Excel File). • An array is a group of consective memory locations with same name and data type. An array is an indexed sequence of values of the same type. • Examples: an array of character models, an array of textures, an array of sounds. The individual elements are An ArrayList in Java represents a resizable list of objects. pptx - Copy.ppt from COMPUTER S 111111 at IIM Bangalore.
