Write a Java program to accomplish each of the following tasks : (a) Add 10 to integer variable x. (b) Declare variable y of type int and initalize to 0. (c) Use one statement to assign the sum of x and y to z, then increment y by 1.

17.Write a Java program that prompts the user to input an integer greater than 0 which represents the size/height of the triangle shape. The program should print the following triangle shape according to the user input by alternating 'f' and '+' characters. Invalid error message must be displayed if the size is less than 1. Example: if the size of the shape = 4, then the p program should output: ! !+! !+!+! 1+1+1+1

NO SAMPLE OUTPUT AVAILABLE. Write a PYTHON program which accomplishes the following tasks: set a variable to the result of mathematical expression including +, -, * and / and of both Integer and Float values (or variables) set a variable to the result of a combination of string values (or variables) set a variable to the result of a combination of string, Integer and Float values (you may need to use the type casting functions) Using the following variables:a = 1.3b = 4iterations = 7 Create a loop which will execute "iterations" times and outputs the result of the following expression:a = a * b reset iterations to 7.  create a loop which executes 'iterations' times and contains the following expression:iterations -= 1 reset iterations to a number between 6 and 12.  Create a loop which executes 'iterations' times and does the following: if Iterations is even: subtract 0.5 from b (output a and b) if iterations is odd: multiply a by b (output a) Demonstrate a while loop which…
