자바 객체 배열 정렬하기

Sample 객체 public class TestVO { private String key; private String value; public String getKey() { return key; } public void setKey(String key) { this.key = key; } public String getValue() { return value; } public void setValue(String value) { this.value = value; } } sorting util public static void sortVOByKey(TestVO [] arrVO) { for (int i = 0; i < arrVO.length - 1; ++i) { TestVO vo = arrVO[i]; for (int j = i + 1; j < arrVO.length; ++j) { TestVO nextVO = arrVO[j]; if (vo.getKey().compareTo(nextVO.getKey()) > 0) { TestVO sortVO = arrVO[i]; arrVO[i] = arrVO[j]; arrVO[j] = sortVO ; } } } }
