Write a Java statement that implements the following algebraic equation assuming that all variables have double data type: z = 5y + 4x³ 3x + 2y² Question 7 (3 mark): 1 ft = 30.48 cm, write a program that converts length in ft into cm and print out. The input is a length in ft typed by user, the output is a length in cm. REQUIREMENTS • The user input is always correct (input verification is not required). Assume each value is in double type. Your code must use the Scanner class to read the user input. • Your code must work exactly like the following example (the text in bold indicates the user input). Example of the program output: Enter length in ft: 12.1 Length 368.808 centimeters Question 8 (3 mark): Implement class Swap Int as follows and complete this incomplete code: class SwapInt { public static void main (String[] args) ( int a Integer.parseInt (args [0]); int b Integer.parseInt(args [1]); System.out.println("Before: " + "a = + a + } -- Please insert your code here for swapping a and b -- */ System.out.println ("After: "+"a = " +a +", b = " + b); "+b); Consider the following steps to swap values stored in a and b: 1. Declare a variable temp (in a way similar to a and b) 2. Assign the variable a to the variable temp 3. Assign the variable b to the variable a 4. Assign the variable temp to the variable b Write a Java statement that implements the following algebraic equation assuming that all variables have double data type: z = 5y + 4x³ 3x + 2y² Question 7 (3 mark): 1 ft = 30.48 cm, write a program that converts length in ft into cm and print out.
