Please solve this in java, using the Gui system(Jframe, Jpanel, etc) from java, not java fx thanks.

For simple usage of GUIs, why would the source codes (shown below) not work?(a) The input/output objects have not been properly handled.(b) The data type of the methods has been defined in a wrong way.(c) The necessary parameters in the methods have not been assigned properly.(d) The flow of execution has been applied in a wrong way. import javax.swing.JOptionPane;public class Palindrome{public static void main(String[] args) //main method{long num1, num2; //variables to store the numbersString inputStr, outputStr; // strings to receive from the user// and displayinputStr=JOptionPane.showInputDialog("Enter the number: ");num1 = Long.parseLong(inputStr); // change the string tonum2 = num1; // numbersif (num1 <= 0){num1 = - num1; //if the numbers are negative, change the sign inputStr = inputStr.valueOf(num1);//change the inputStr value } if (isPalindrome(inputStr))outputStr = num2 + " is a palindrome";elseoutputStr = num2 + " is not a palindrome";JOptionPane.showMessageDialog(null,…

What exactly do we mean when we talk about "encapsulation" while talking about object-oriented methods?

In JavaScript, how are an object and an interface related to each other? a. The object’s interface consists of the code and data needed for that object. b. An object’s interface is analogous to a pocket calculator’s inner workings. c. Built-in JavaScript objects do not require an interface, but custom objects do. d. An interface allows another program to access an object’s properties and methods.
