Creating Arrays In Java
Categories: Java 8(JDK1.8)
You can create an array by using the new operator with the following syntax −
Syntax
arrayRefVar = new dataType[arraySize];
The above statement does two things −
It creates an array using new dataType[arraySize].
It assigns the reference of the newly created array to the variable arrayRefVar.
Declaring an array variable, creating an array, and assigning the reference of the array to the variable can be combined in one statement, as shown below −
dataType[] arrayRefVar = new dataType[arraySize];
Alternatively you can create arrays as follows −
dataType[] arrayRefVar = {value0, value1, ..., valuek};
The array elements are accessed through the index. Array indices are 0-based; that is, they start from 0 to arrayRefVar.length-1.
