Data Structure: Array Data Structure using Java
Objective
Learn about arrays
Explore how to declare and manipulate data into arrays
Understand the meaning of “array index out of bounds”
Become familiar with the restrictions on array processing
Learn about multidimensional arrays
Array is the simplest data structure where each data element can be randomly accessed by using its index number. For example, if we want to store the marks of a student in 6 subjects, then we don't need to define different variable for the marks in different subject.
