![]() To initialize an Array with default values in Java, the new keyword is used with the data type of the Array The size of the Array is then placed in the rectangular brackets. Initializing an Array with default values The Array initialization process includes assigning an initial value to every element in the Array. As an Array consists of multiple values, its initialization process is not as simple as a variable. Initialize an Array in JavaĪfter a declaration, the Array has to be initialized just like any other variables. It can be considered as the address of the Array in the memory. This is where a memory address is just assigned to the Array. It is because here only an Array reference is created in the memory. You must have noticed that the size of the Array is not mentioned in the declaration process. ![]() The additional part is the addition of rectangular brackets to denote that it is an Array.įollowing are the two basic ways to declare an Array: int myArr īoth ways are valid but the first method is more commonly used. It is done by providing an identifier (name) and the data type. It is initially set when an Array is declared and after that, it cannot be altered.Īn Array is declared in a very similar way to other variables are declared. The only limitation in the Array is of size. Each element has a unique index value that is used to access the data stored in them. The values stored in the Array are referred to as elements. Along with exploring a way to declare an Array, we will mainly be discussing various methods used to initialize an Array with values in Java. In this article, we will be discussing how to use Arrays in Java. It is one of the most fundamental data structures in Java and is used for implementing almost every type of algorithm. An Array is a collection of data objects consisting of the same data type. ![]() Java offers a variety of data structures for developers to work with.
