Literal is just unlikely any constant value that can be assigned to a variable

In Java, an array is a collection of elements of the same data type, stored in contiguous memory locations. Array literals, also known as array initializers, are a convenient way to create and initialize an array in a single statement.

An array literal is a comma-separated list of values enclosed in curly braces { }. For example, the following code creates an array of integers and initializes it with the values 1, 2, 3, 4, and 5: 

int[] numbers = {1, 2, 3, 4, 5};

In this example, the type of the array is int[], which means it is an array of integers. The curly braces { } enclose the list of values that will be stored in the array. Each value is separated by a comma, and the entire list is enclosed in the curly braces. The size of the array is determined by the number of values in the array literal.

Array literals can also be used to create arrays of other data types, such as strings, booleans, or objects. For example, the following code creates an array of strings and initializes it with three string literals: 

String[] names = {"Alice", "Bob", "Charlie"};

In summary, array literals are a convenient way to create and initialize arrays in Java. They allow you to declare and populate an array in a single statement, which can save time and make your code more concise.
