I wanted to know how to do an algorithm where I entered a year, and the value increased with age, like year 2016 = 1, year 2017 = 2, in a method.

Something like this:

int fazAniversidade(int ano) {
    if(ano == 2015) {
        this.idade +=1;
    }
    if(ano == 2016) {
        this.idade +=2;
    }

    return 0;

 }

But in a loop, how to do it?

It does not make sense to return 0 (zero) if the intention is only to set this.idade = x . In this case, use void in the function.

You do not need to use loop , just take the difference between the current year and the year entered in the function call.

Result

Main.java

import java.util.Calendar;

public class Main
{

    static int idade;

    public static void main(String[] args)
    {
        idade = 10;
        fazAniversidade(2015); // seta idade = 11
        //fazAniversidade(2016); // seta idade = 12
        //fazAniversidade(2017); // seta idade = 13
    }

    public static void fazAniversidade(int ano)
    {
        int ano_atual = Calendar.getInstance().get(Calendar.YEAR);
        int diferenca = (ano - ano_atual) + 1;

        idade += diferenca;
    }
}
