2 Write Java statements that accomplish the following a Declare int variables x and y b. Update the value of an int variable x by adding to it. Declare and initialize a double variable payRate to 12.50 d. Copy the value of an int variable firstNum into an int variable tempNum. e Swap the contents of the int variables x and y. Declare additional variables, if necessary. Declare a char variable grade and set the value of grade to 'A'. C 3. What is the output of the following statements? Suppose a and b are int variables, c is a double variable, and a = 13.6-5. and c = 17.5. a. System.out.println("a + b + c = "= a + b + c): b. System.out.println (15 / 2 + c); c. System.out.println(a (deuble) (b+ 2 + c): d. Syatem.out.println (14 5 3 + 6.3 + ba): e. System.out.println() e Sa - b); 1. System.out.println 13.5 / 2 + 4.0 - 3.5 + 18)
