Java Method called triangle that prints following triangle pattern.   You should use for loop.   Hint: https://youtu.be/5TIUbp9_xvM   1 12 123 1234 12345

8) Now use the Rectangle class to complete the following tasks: - Create another object of the Rectangle class named box2 with a width of 100 and height of 50. Note that we are not specifying the x and y position for this Rectangle object. Hint: look at the different constructors) Display the properties of box2 (same as step 7 above). - Call the proper method to move box1 to a new location with x of 20, and y of 20. Call the proper method to change box2's dimension to have a width of 50 and a height of 30. Display the properties of box1 and box2. - Call the proper method to find the smallest intersection of box1 and box2 and store it in reference variable box3. - Calculate and display the area of box3. Hint: call proper methods to get the values of width and height of box3 before calculating the area. Display the properties of box3. 9) Sample output of the program is as follow: Output - 1213 Module2 (run) x run: box1: java.awt. Rectangle [x=10, y=10,width=40,height=30] box2: java.awt.…

Java Code Write a Windspeed class that stores the total winsoeed for each of 12 months into an array of double windspeedmeasures. The windspeed shoukd be collected from the user. The program should have methods that return the following: - total windspeed fir the year - the average monthly windspeed (Include single line comments and populating the array with a Scanner)

Charge Account ValidationCreate a class with a method that accepts a charge account number as its argument. The method should determine whether the number is valid by comparing it to the following list of valid charge account numbers:5658845    4520125    7895122    8777541    8451277    13028508080152    4562555    5552012    5050552    7825877    12502551005231    6545231    3852085    7576651    7881200    4581002These numbers should be stored in an array. Use a sequential search to locate the number passed as an argument. If the number is in the array, the method should return true, indicating the number is valid. If the number is not in the array, the method should return false, indicating the number is invalid.Write a program that tests the class by asking the user to enter a charge account number. The program should display a message indicating whether the number is valid or invalid.

Repeating String Write a method that takes a String and an int and return a String that is the original String repeated n times. For example, repeatString("Famous", 3) should return "FamousFamousFamous" The method signature should be public String repeatString(String str, int n)   public String repeatString(String str, int n) { //declare a string variable   //set up statements for repeating n number of times         //create the appropriate return statement   }

public class Program7 {   publicstaticvoidmain(String[]args){ int[]numbers=newint[100]; String[]names={"Maria","Aris","Galin","Galena"}; double[]balances=newdouble[]{2,56,12.57,36.57,57.89};   //length System.out.println(numbers.length); System.out.println(names.length); System.out.println(balances.length);   //modifying names[3]="Celine Dion"; System.out.println("__________________________");   //looping for(inti=0;i<names.length;i++){ System.out.println(names[i]); } System.out.println("__________________________"); for(Stringname:names){ System.out.println(name); }   //modifying array System.out.println("__________________________"); for(inti=0;i<names.length;i++){ names[i]=names[i]+" Annan"; System.out.println(names[i]); }   System.out.println("__________________________"); doubletotal=0.0; for(inti=0;i<balances.length;i++){ total+=balances[i];   }   System.out.println("Total Balance: "+ total); } } //calculate the average of the total balance

for the class ArrayAverage write a code that calculates the average of the listed numbers with a double result for the class ArrayAverageTester write a for each loop and print out the result

PYTHON!! class Triangle:        def __init__(self,sides):                self.a = sides[0]        self.b = sides[1]        self.c = sides[2] if __name__ == '__main__':       t = Triangle([3,6,2])        print(f'Side1 = {t.a}')    print(f'Side2 = {t.b}')    print(f'Side3 = {t.c}') Based on the code.  Assume you are in the Triangle class: Create a method called calcArea.  It will calculate and return the area of the triangle using this formula:

import java.awt.*; public class TestRectangle {public static void main(String[] args) {Rectangle r1 = new Rectangle(5, 4, 10, 17);Rectangle r2 = new Rectangle(10, 10, 20, 3);Rectangle r3 = new Rectangle(0, 1, 12, 15);Rectangle r4 = new Rectangle(10, 10, 20, 3);System.out.println("r1 = " + r1);System.out.println("r2 = " + r2);System.out.println("r3 = " + r3);System.out.println("r2 equals r1?
