Java Single Dimensional Arrays are essential for storing fixed numbers of elements in a linear structure. They are created by declaring and allocating memory, and can be initialized with values. These arrays facilitate data storage, retrieval, and statistical computations like standard deviation. Understanding their use is crucial for Java developers.

Array Declaration Syntax in Java
'int[] arr;' declares an array variable without allocating memory.
02
Array Initialization with Values
'int[] arr = {10, 20, 30, 40, 50};' declares, allocates, and initializes an array.
