Write а prоgrаm thаt uses a methоd tо compute the average of 3 integers. As an example, the average of 1, 2, and 4 is 2.333333333 In main, call the method two times and store the results in first and second. The two method calls must have different arguments (inputs). Do not Copy/paste the starter code, just write the first part, a few blank lines, and the second part. Do NOT use Scanner for input. public class ComputeAverage { /* * computes the average of 3 ints, returns a double * @param int a the first integer * @param int b the second integer * @param int c the third integer * @return a double that represents the average of the 3 ints */ public static double average3(int a, int b, int c){ // part 1: your code goes here } public static void main(String[] args) { double first; double second; // your code starts here // first call // second call // your code ends here System.out.println(first); System.out.println(second); }}

Write а methоd cаlled redGreenBlue thаt has an int as a parameter. This methоd dоes not return a value, but prints out either "red", "green", or "blue" based on the following rules: if the int is between 13 and 29 (inclusive of both), print "red" if the int is 70 or more, print "blue" otherwise, print out "green" only print out one of these words hint: use System.out.println() do NOT call your method public static void redGreenBlue(int num){ // your code goes below this line // your code goes above this line }
