need some help with the following java problems (I need a flowchart along with a code)

1. We have a loud talking parrot. The "hour" parameter is the current hour time in the range 0..23. We are in trouble if the parrot is talking and the hour is before 7 or after 20. Return true if we are in trouble.

2. Given 2 ints, a and b, return true if one if them is 10 or if their sum is 10.

3. Return true if the given non-negative number is a multiple of 3 or a multiple of 5. HINT: Use the % "mod" operator as discussed in class
