Sorting array of objects by field

Question

I have objects

Person{
    String name;  
    int age;
    float gradeAverage;
    }

Is there an easy way to sort

Person[]         


        

Answer 1

import java.util.Arrays;

public class PersonCompare {

public static void main(String[] args) {
    Person p1 = new Person("Test1",10);
    Person p2 = new Person("Test2",12);
    Person p3 = new Person("Test3",4);
    Person p4 = new Person("Test4",7);

    Person[] ArrayOfPersons = {p1,p2,p3,p4};
    Arrays.sort(ArrayOfPersons);

    for(Person p: ArrayOfPersons) {
        System.out.println(p.getName()+"--"+p.getAge());
    }
}
}


class Person implements Comparable {
String name;
int age;

Person(String name, int age){
    this.name=name; this.age=age;

}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public int getAge() {
    return age;
}

public void setAge(int age) {
    this.age = age;
}


@Override
public int compareTo(Person other) {
    if(this.getAge() > other.getAge())
        return 1;
    else if (this.getAge() == other.getAge())
        return 0 ;
    return -1 ;
}
}
