- Write an Java application that determines whether a phrase entered by the user is a palindrome. A palindrome is a phrase that reads the same backward and forward without regarding capitalization or punctuation. For example, “Dot saw I was Tod”, “Was it a car or a cat I saw?”, and “Madam, I’m Adam” are palindromes. Display the appropriate feedback: You entered a palindrome or You did not enter a palindrome. import java.util.*; public class Palindrome { public static void main(String[] args) { // Write your code here } }Write a program that simulates a traffic light. The program lets the user select one of three lights: red, yellow, or green. When a radio button is selected, the light is turned on. Only one light can be on at a time (see Figure (b)). No light is on when the program starts. Using java programmingJAVA PROGRAMA bank offers a 3% interest per annum for savings accounts. The bank also has 1% withholding tax per annum.

If the input number is outside of this range, output a message "Invalid Input" and exit the program. If its a valid number: Check if the square of the sum of its digits is equal to the input number If the square of the sum of its digits is not equal to the input number, find the reverse of the number and display it. For example: Input: 81 Output: 81 because 81 = (8 + 1)2 Input: 23 Output: 32 because 23 is not equal to (2 + 3)2
- java Write a program that prompts the user to enter a point (x, y) and checks whether the point is within the rectangle centered at (0, 0) with width 10 and height 5. For example, (2, 2) is inside the rectangle and (6, 4) is outside the rectangle, as shown in the Figure. (Hint: A point is in the rectangle if its horizontal distance to (0, 0) is less than or equal to 10 / 2 and its vertical distance to (0, 0) is less than or equal to 5 / 2.) Here are sample runs of the program: Sample 1: Enter a point with two coordinates: 2 2 Point (2.0, 2.0) is in the rectangle Sample 2: Enter a point with two coordinates: 6 4 Point (6.0, 4.0) is not in the rectangle Analysis: (Describe the problem including input and output in your own words.)

The program begins by showing the menu and promoting the user to enter a choice. If the user enters 1, 2, 3, 4, or 5, the program responds by asking the quantity of order. If the user enters a number outside the range 1 -5, the program prints an error message, then ask the user to enter a new choice. The program “loops” until the user select 0 to exit the menu. Finally, the program displays a summary of the user’s order. Your program output should resemble the sample runs as following. Welcome to our Cafe!
