Here are some key points to help you understand arrays: Definition: An array is a data structure that stores a fixed-size sequence of elements of the same type. It provides a way to organize and access multiple values using a single variable name. Declaration and Initialization: In Java, you declare an array by specifying the type of elements it will hold, followed by square brackets ([]), and the array name.
