(Convert decimals to fractions)Write a program that prompts the user to enter a decimal number and displays the number in a fraction.Hint: read the decimal number as a string, extract the integer part and fractional part from the string, and use the Rational class in LiveExample 13.13 to obtain a rational number for the decimal number. Use the template athttps://liveexample.pearsoncmg.com/test/Exercise13_19.txt
The problem can not use BigInteger
//Below is the Rational LiveExample 13.13 that goes with the problem/question; notice "long" instead of "BigInteger"
class Rational extends Number implements Comparable<Rational> { // Data fields for numerator and denominator private long numerator = 0; private long denominator = 1;
/** Construct a rational with default properties */ public Rational() { this(0, 1); }
/** Construct a rational with specified numerator and denominator */ public Rational(long numerator, long denominator) { long gcd = gcd(numerator,…

Sample Run 1
Enter a series of numbers ending with 0:2 4 4 8 8 8 8 2 4 4 0The longest same number sequence starts at index 3 with 4 values of 8
Sample Run 2
Enter a series of numbers ending with 0: 34 4 5 4 3 5 5 3 2 0

4. Random walkers. Write a program
RandomWalkers.java that takes two
integer command-line arguments r
and trials. In each of trials
independent experiments, simulate
a random walk until the random
walker is at Manhattan distance r
from the starting point. Print the
average number of steps.
-/Desktop/loops> java Randomwalkers 5 1000000
average number of steps = 14.98188
-/Desktop/loops> java Randomlalkers 5 1000000
average number of steps = 14.93918
-/Desktop/loops> java Randomlalkers 10 100000

As r increases, we expect the
random walker to take more and
more steps. But how many more
steps? Use RandomWalkers.java…

Implement the bin2Dec method to throw a NumberFormatException if the string is not a binary string. Write a test program that prompts the user to enter a binary number as a string and displays decimal equivalent of the string. If the method throws an exception, display "Not a binary number".Sample Run 1Enter a binary number: 1015Sample Run 2Enter a binary number: 41Not a binary number: 41arrow_forward(YOU ARE NOT ALLOWED TO USE ARRAYLIST IN THIS PROJECT)Write a Java program to simulate a blackjack game of cards. The computer will play the role of the dealer. The program will randomly generate the cards dealt to the player and dealer during the game. Cards in this game will be represented by numbers 1 to 13 with Ace being represented by a 1. Remember, that face cards (i.e. Jack, Queen, and King) are worth 10 points to a hand while an Ace can be worth 1 or 11 points depending on the user’s choice. The numbered cards are worth their number value to the hand.arrow_forward

Display the students’ questions for each studentarrow_forward(Recursion and Backtracking) Write the pseudo code for a recursive method called addB2D that takes two binary numbers as strings, adds the numbers and returns the result as a decimal integer. For example, addB2D(‘‘101’’, ‘‘11’’) should return 8 (because the strings are binary representation of 5 and 3, respectively). Your solution should not just simply convert the binary numbers to decimal numbers and add the re- sults. An acceptable solution tries to find the sum by just directly processing the binary representations without at first converting them to decimal values.arrow_forward

Based on the size entered, write a loop which asks the user to fill values into an integer array. Print the array contents using Arrays.toString(). For this integer array, write a logic that returns true if there exists a place to split the array such that the sum of the numbers on one side is equal to the sum of the numbers on the other. Otherwise return false. Examples: If the array is {1, 1, 1, 2, 1} then return true. If the array is {2, 1, 1, 2, 1} then return false If the array is {10, 10} then return true.arrow_forward- Do not add any imports, the ones that you need will be given to you.- Do not use recursion.- Do not use break/continue.- Do not use try-except statements, you should be able to anticipateor prevent any errors from happening at all!arrow_forward

For this integer array, write a logic that returns true if there exists a place to split the array such that the sum of the numbers on one side is equal to the sum of the numbers on the other.
