Java array is an object which contains elements of a similar data type.
Additionally,The elements of an array are stored in a contiguous memory
location.
Basically, it is one of the a data structure where we store similar elements.
We can store only a fixed set of elements in a Java array.
following shows the use of the array in java,int a[]=newint[5];//declaration and instantiation
a[0]=10;//initialization
a[1]=20;//after printing arraydefault value of arrray element is 0;[10,20,0,0,0]
String[] cars ={"Volvo","BMW","Ford","Mazda"};System.out.println(cars[0]);// Change elements in array
cars[0]="Opel";System.out.println(cars[0]);// Length of arraySystem.out.println(cars.length);// Loop through arrayfor(int i =0; i < cars.length; i++){System.out.println(cars[i]);}
