Varying the order of method calling for different instances of a class

Question

What is the best way of manipulating the order things are done based on some conditions (other than writing them again with the different order)?

Let's say there is a Person class and each object of Person represents a different human.

class Person{
    int eatingPriority = 3;
    int sleepingPriority = 2;
    int recreationPriority = 1;

    void eat() {/*eats*/}
    void sleep() {/*sleeps*/}
    void watchTv() {/*watches tv*/}

    void satisfyNeeds() {
        //HOW TO DO THIS
    }
}

How can I make the satisfyNeeds() methods call the other three methods based on their priority?

Note: I want to make it clear that priorities can change from Person to Person.

Answer 1

You can use this code

import java.util.Arrays;  // must be imported
int[] priorities = {sleepPriority, eatPriority, recreationPriority};
Arrays.sort(priorities);
for (int i=priorities.length-1; 0<=i; i--) {
    int priority = priorities[i];
    if (priority == sleepingPriority) { sleep(); }
    if (priority == eatingPriority) { eat(); }
    if (priority == recreationPriority) { watchTv(); }
}

Basically, it puts the priorities in an array, sorts the array and runs a for loop on it to run the functions.
