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.
How can you create array of an object in java?
Array's can hold only primitive data types. if you want a collection of objects you must use an ArrayList or a Vector.
How do you declare an array of buttons in Java?

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 do you accept an array in java?
Arrays are objects in Java that store multiple variables of the same type. Arrays can hold either primitives or object references, but the array itself will always be an object on the heap, even if the array is declared to hold primitive elements. In other words, there is no such thing as a primitive array, but you can make an array of primitives. Arrays are declared by stating the type of element the array will hold, which can be an object or a primitive, followed by square brackets to the left or right of the identifier. Declaring an array of primitives: int[] Values; // brackets before name (recommended) int Values []; // brackets after name (legal but less readable)
How can you initialize an array in Java?
If you refering to Object then String[] something=new String[2]; Here you have to remember that something only allocated space for 2 String object but it did not created them yet.

Are arrays objects?

Argument Array in java script?
There is an arguments object in JavaScript. This object is treated much like an array (but it's not actually an array.)You can however reference the arguments passed to a function via this array. For instance, if we call a function like so:exampleFunc('Tom', 15, 'potato');Then we can access the value of Tom at the local variable arguments[0].
How do you delete an array object in java language?
The Java Virtual Machine takes care of all the actual deletion for you. Once an object no longer has any references left, the garbage collector will come along and clear up that memory automatically.
Can an array contain elements of an object type?
Yes. An array of arrays is nothing more than a multi-dimensional array.
