4. i. Write a single Java statement to find the largest value of three integer variables a, b and c. If the variable num1 is equal to 5 and the variable num2 is equal to 10, what will be value of the logical expression ((num1 != 5) || (num2 == 10)) && !(num1 ==5) ? ii. iv. Create an array that can hold 50 double type values. Now, write a for loop that initializes the array to the values 50.0 through 99.0. Write a while, a do-while and a for loop that will count backwards from 20 to 10.
