Fixed number of values of same data type. Syntax: datatype nameOfVariable[] = new dataType[size];
- int[] arr = new int[size];
- int []arr = new int[size];
- int arr[] = new int[size];
int arr[] = new int[5]; => Indexes are always start from 0; => ith index = arr[i]
Access first and last elements: arr[0] & arr[n-1]
Note: There are not heterogeneous arrays in java.
- Properties:
-
int arr[] = new int[5]; Ex: System.out.print(arr.length); //5
-
By default all the elements are initialized with 0;
Ex:
-
for(int i=0; i< arr.length; i++){ System.out.println(arr[i]); } output: 0 0 0 0 0
-
float arr[] = new float[5]; for(float i=0; i< arr.length; i++){ System.out.println(arr[i]); } output: 1.0 2.0 3.0 4.0 5.0
-
double arr[] = new double[5]; for(double i=0; i< arr.length; i++){ System.out.println(arr[i]); } output: 1.0 2.0 3.0 4.0 5.0
Note: Java cannot have negative indexing as it will throw error.
