Example: Access Array Elements class Main , Let's see an example of accessing array elements using index numbers. Here is the syntax for accessing elements of an array, // access array elements We can access the element of an array using the index number. We can also initialize arrays in Java, using the index number. In the Java array, each memory location is associated with a number. ![]() In this case, the Java compiler automatically specifies the size by counting the number of elements in the array (i.e. Note that we have not provided the size of the array. Here, we have created an array named age and initialized it with the values inside the curly brackets. For example, //declare and initialize and array In Java, we can initialize arrays during declaration. In Java, we can declare and allocate the memory of an array in one single statement. We can also say that the size or length of the array is 10. Good question! To define the number of elements that an array can hold, we have to allocate memory for the array in Java. Here, data is an array that can hold values of type double.īut, how many elements can array this hold? dataType - it can be primitive data types like int, char, double, byte, etc.In Java, here is how we can declare an array. The number of values in a Java array is always fixed. Here, the above array cannot store more than 100 names. An array is a collection of similar types of data.įor example, if we want to store the names of 100 people then we can create an array of the string type that can store 100 names.
