Array declaration in java. We can access elements of an array by using those indices. No size limit is considered for this. A java array variable can also be declared like other variables with after the data type. Java array is an object which contains elements of a similar data type. The variables in the array are ordered and each have an index beginning from 0. Java provides a data structure the array which stores a fixed size sequential collection of elements of the same typean array is used to store a collection of data but it is often more useful to think of an array as a collection of variables of the same type.
Java array can be also be used as a static field a local variable or a method parameter. In the image we can see that each element consists of a number array index. Instead list is most encouraged to declare a static array of integer string float etc. Normally an array is a collection of similar type of elements which has contiguous memory location. For example int age new int5. Here we have an array of length 5.
Use the bellow declaration and initialization statements. In this section you will learn how to declare array in java. Java array declaration as we declare a variable in java an array variable is declared the same way. In this section you will learn how to declare array in java.
