Java collection multi fields sorting

Sorting a list by multiple fields using Comparator on the Collection. For example, a list of person object which has name and age, group the list by name and then sort the person within that name by age.

Input:

Name: ccc Age: 51
Name: ccc Age: 35
Name: aaa Age: 19
Name: bbb Age: 7
Name: bbb Age: 94
Name: bbb Age: 60
Name: aaa Age: 85
Name: bbb Age: 49
Name: aaa Age: 82

Output:

Name: aaa Age: 19
Name: aaa Age: 82
Name: aaa Age: 85
Name: bbb Age: 7
Name: bbb Age: 49
Name: bbb Age: 60
Name: bbb Age: 94
Name: ccc Age: 35
Name: ccc Age: 51

The Person.java

public class Person implements Comparable {
	private String name;
	private int age;
	
	public Person(String n, int a) {
		this.name = n;
		this.age = a;
	}
	
	public String toString() {
		return "Name: " + name + " Age: " + age;
	}
	
	public String getName() {
		return name;
	}
	
	public int getAge() {
		return age;
	}
	
	
    @Override
    public int compareTo(Person another) {
    	
        int sComp = this.name.compareTo(another.name);
        // sort by name first and then age
        if (sComp != 0) {
           return sComp;
        } else {
           Integer age1 = this.getAge();
           Integer age2 =  another.getAge();
           return age1.compareTo(age2);
        }

    }
}
