大文字の全てのアルファベットをアルファベット順で取得する

実装 - Implementation

import java.util.ArrayList;
import java.util.List;

public class AlphabetUtil {
	public static List<String> getUpperAlphabets() {
		final int ALPHABET_SIZE = 'Z' - 'A';
		char alphabet = 'A';
		
		List<String> upperAlphabets = new ArrayList<String>();
		for (int i = 0; i <= ALPHABET_SIZE; i++) {
			upperAlphabets.add(String.valueOf(alphabet++));
		}
		return upperAlphabets;
	}
}

テスト - Test

import java.util.List;

import org.junit.Test;
import static org.junit.Assert.*;

public class AlphabetUtilTest {
	
	@Test
	public void shouldGetAllUpperAlphabetInAlphabeticalOrder() {
		List<String> alphabets = AlphabetUtil.getUpperAlphabets();
		assertEquals("A", alphabets.get(0));
		assertEquals("B", alphabets.get(1));
		assertEquals("C", alphabets.get(2));
		assertEquals("D", alphabets.get(3));
		assertEquals("E", alphabets.get(4));
		assertEquals("F", alphabets.get(5));
		assertEquals("G", alphabets.get(6));
		assertEquals("H", alphabets.get(7));
		assertEquals("I", alphabets.get(8));
		assertEquals("J", alphabets.get(9));
		assertEquals("K", alphabets.get(10));
		assertEquals("L", alphabets.get(11));
		assertEquals("M", alphabets.get(12));
		assertEquals("N", alphabets.get(13));
		assertEquals("O", alphabets.get(14));
		assertEquals("P", alphabets.get(15));
		assertEquals("Q", alphabets.get(16));
		assertEquals("R", alphabets.get(17));
		assertEquals("S", alphabets.get(18));
		assertEquals("T", alphabets.get(19));
		assertEquals("U", alphabets.get(20));
		assertEquals("V", alphabets.get(21));
		assertEquals("W", alphabets.get(22));
		assertEquals("X", alphabets.get(23));
		assertEquals("Y", alphabets.get(24));
		assertEquals("Z", alphabets.get(25));
	}
	
}
