To declare an array of buttons in Java, you would use the following syntax:
Button[] buttonArray = new Button[n];
where n is the number of buttons you want in the array. This creates an array of n buttons, where each element can hold a reference to a Button object.

How do you initialize an array variable in java program?
An array in java is a collection of items stored into a single unit. The array has some number of slots (elements), each slot in the array can hold an object or a primitive value. Arrays in java are objects that can be treated just like other objects in the languageArrays can contain any type of element value , but we can't store different types in a single array. We can have an array of integers or an array of strings or an array of arrays.To create an array in java ,use three steps1. Declare a variable to hold the array2. Create a new array object and assign it to the array variable3. Store things in that array
How many dimensions you can declare in array?
It seems that the number of allowed array dimensions is implementation specific and not set by the Java specifications. I'm sure that any Java implementation will allow a reasonable number of dimensions for any project you have. After a quick test, it seems that Java is not limited by an arbitrary number so much as a practical value. If you add hundreds of array dimensions, Java will allow you to do so as long as you have enough memory allocated for Java. After a bit of copy-pasting the program no longer ran, exiting with a StackOverflowError.
You can use a variable to declare an array's size true or false?
True and false in the same time, because even so you can declare array size using notation for variables you have use constwhich makes your variable basically a constant:const int arraySize = 10;In Java, you can use any expression to define the array size, when you create the array. Once you create an Array object, however, you can't redimension it - but you can create a new Array object and destroy the old one.
Create an array of 10 elements in java?
to create a new Java array use typeName[] arrayName = new typeName[10]; This gives an array with 10 elements. To set the elements you can use arrayName[index] = value; Remember that the index number starts at 0, so the array will only go to index 9. You can also declare the contents when the array is created typeName[] arrayName = {value1, vaue2, ...} The values used in the array must be objects. In java 5+ you can use primitive types with no concern due to auto-boxing.
