Fixed size array vs arraylist conversion gui

Now, Let us take a Class Student that has two properties its Name and Age. We have discussed ArrayList example with Pre Defined Data types like Integer and String types, now let us discuss Arraylist of User Defined Class. In Step 3, we have displayed values of these objects.Д®xample 2: ArrayList Of User-Defined Objects:.In Step 2, we have used add method to store values in the data structures that we have created in step 1.In Step 1, we have created two objects of ArrayList Class, first object stores value of String type, Second of Integer type.Let us discuss ArrayList with the help of program, In this program we have created two objects that store predefined data types that are of Integer and String type, following program is divided into 3 steps that are discussed below: import java.util.* ('aList doesn't contains element 5') Д®xample 1: ArrayList of Pre Definded Data types: This method returns true if the calling ArrayList object contains the specific element as given in the argument list, otherwise it returns false.Д«elow is the example program of boolean contains(Object element) method is as: import Output: aListCopy elements copied from aList1=

('aListCopy elements copied from aList1= '+aListCopy) Using clone() method to copy aList1 into a new aListCopy ArraylistДЄrrayList aListCopy = (ArrayList) aList1.clone() This method returns the exact same copy of the arraylist object.Д«elow example helps us to understand this method easily: import Printing aList element after using clear method= Output: Printing aList items before using clear method= ('size of aList1 after clear() method= ' + aList.size())

('Printing aList element after using clear method= '+aList) ('Printing size of aList1= ' + aList.size()) ('Printing aList items before using clear method= '+aList) let us print all the elements available in aList use add() method to add elements in the list This method remove all the elements of the arraylist.Д«elow the example program clear() method shows the working of this method: import Output: Integer Number Added in ArrayList= ('Integer Number Added in ArrayList= ' + aList)

The Example program of this boolean add(Object o) method is as: import It returns True if element is successfully added, and returns false if it is not.It adds an element of Specific Object type at the end of Arraylist as no index is mentioned in the method.
