- Q1) Write a method that checks whether two words are anagrams. Two words are anagrams if they contain the same letters in any order. For example, "silent" and "listen" are anagrams. Write a test program that prompts the user to enter two strings and, if they are anagrams, displays "anagram", otherwise displays "not anagram". Note: The header of the method is as follows: public static boolean isAnagram(String s1, String s2) Sample Input #1: Enter two strings: Silent listen Sample Output #1: The string “Silent” and “listen” are anagrams. Sample Input #1: Enter two strings: teach peach Sample Output #1: The string “teach” and “peach” aren’t anagrams.arrow_forwardX3: inlTo10 Write a function in Java that implements the following logic: Given a number n, return true if n is in the range 1..10, inclusive. Unless "outsideMode" is true, in which case return true if the number is less or equal to 1, or greater or equal to 10.arrow_forwardQ3: (Tax Calculator) Develop a Java program that determines the total tax for each of four citizens. The tax rate is 10% for earnings up to 50,000 RM earned by each citizen and 15% for all earnings in excess of that ceiling. You are given a list with the citizens’ names and their earnings in a given year. Your program should input this information for each citizen, then determine and display the citizen’s total tax. Use class Scanner to input the data.arrow_forward

- (Game: scissor, rock, paper) Write a program that plays the popular scissor–rock–paper game. Rules: A scissor can cut a paper, a rock can knock a scissor, a paper can wrap a rock. The program should randomly generates a number 0, 1, or 2 representing scissor, rock, and paper. The program should prompt the user to enter a number 0, 1, or 2 and displays a message indicating whether the user or the computer WINs, LOSEs, or DRAWs.arrow_forward7) The ideal gas law allows the calculation of volume of a gas given the pressure(P), amount ofthe gas (n), and the temperature (T). The equation is:V = nRT / PSince we only have used integer arithmetic, all numbers will be integer values with nodecimal points. The constant R is 8.314 and will be specified as (8314/1000). This givesthe same result. Implement the idea gas law program where the user is prompted for andenters values for n, T, and P, and V is calculated and printed out. Be careful toimplement an accurate version of this program. Your program should include a properand useful prompt for input, and print the results in a meaningful mannerarrow_forwardpython nMath: pentagonal numbers) A pentagonal number is defined as n(3n-1)/2 for n=1,2,..., and so on. So, the first few numbers are 1, 5, 12, 22, ....

- 1)-Write a Java program that reads values for three sides of a triangle. The sides will form atriangle if the values are greater than zero and the sum of any two sides is greater than thethird side. The program should classify the triangle as either isosceles, scalene, equilateral, orboth right-angled and scalene according to the following rules:• An equilateral triangle has all sides equal• An isosceles triangle has only two sides equal• A scalene triangle has no sides equal• In a right-angled triangle, the square of the longest side must be equal to the sumof the squares of the other two sides. (i.e., if c is the longest side among sides a, band c of a right-angled triangle then c2 = a2 + b2). Here are some specific requirements:• Include a boolean method named checkTriangle, which accepts threedouble values as arguments and returns true if they form a triangle (otherwisereturns false)• Include a value returning method named getLongest, which accepts threedouble values as arguments…arrow_forward) The Bahraini Charity Club is conducting a fundraiser by selling chilli dinners to go.The price is BD2.1 for an adult meal and BD1.2 for a child’s meal.Write a Java program that accepts the number of each type of meal ordered and displaythe total money collected for adult meals, children’s meals and all meals.arrow_forwarddef winning_card(cards, trump=None): Playing cards are again represented as tuples of (rank,suit) as in the cardproblems.pylecture example program. In trick taking games such as whist or bridge, four players each play one card from their hand to the trick, committing to their play in clockwise order starting from the player who plays first into the trick. The winner of the trick is determined by the following rules:1. If one or more cards of the trump suit have been played to the trick, the trick is won by the highest ranking trump card, regardless of the other cards played.2. If no trump cards have been played to the trick, the trick is won by the highest card of the suit of the first card played to the trick. Cards of any other suits, regardless of their rank, are powerless to win that trick.3. Ace is the highest card in each suit.Note that the order in which the cards are played to the trick greatly affects the outcome of that trick, since the first card played in the trick…arrow_forward
