22.02.20_자바와스프링에서찾아보는패턴

01.자바

01.1 StrategyInJava

import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;

public class StrategyInJava{
    
    public static void main(String[] args){
        List<Integer> numbers = new ArrayList<>();
        numbers.add(10);
        numbers.add(5);
        
        Collections.sort(numbers, new Comparator<Integet>(){
			@Override
            public int compare(Integer o1, Integet o2){
                return o1 - o2;
            }
        });
        //Collections.sort(numbers, Comparator.reverseOrder());
        //Collections.sort(numbers, Comparator.naturalOrder());

        System.out.println(numbers);
    }
}

02.스프링

• 스프링의 경우에는 너무 많음
