应用排序后,我按照排序方式得到一些句子,而在其他句子中,所有单词都被排序,但除了第一个单词。 例如,Amako; Jun(Shiojiri,JP),Umetsu; Kazushige(Chino,JP),Tanaya;英雄(Su访,JP)
青木; Shigenori(川崎,JP),加藤; Masayuki(川崎,JP)
De Dobbelaere;彼得(加利福尼亚州圣地亚哥),Pinguet;蒂埃里(华盛顿州阿灵顿),彼得森;马克(加利福尼亚州圣地亚哥),哈里森;马克(埃斯孔迪多,加州),迪金森; Alexander G.(Laguna Beach,CA),Gunn,III; Lawrence C.(Encinitas,CA)
输出是 - Hideo(Suwa,JP)Jun(Shiojiri,JP),Umetsu Kazushige(Chino,JP),Tanaya Amako
Masayuki(Kawasaki,JP)Shigenori(Kawasaki,JP),Kato Aoki
Alexander G.(Laguna Beach,CA),Gunn,III Lawrence C.(Encinitas,CA)Mark(Escondido,CA),Dickinson Mark(San Diego,CA),Harrison Peter(San Diego,CA),Pinguet Thierry(华盛顿州阿灵顿),Peterson De Dobbelaere
代码示例:
ResultSet rs = stmt.executeQuery(sql);
List<String> results = new ArrayList<String>();
while (rs.next()) {
results.add(rs.getString(1));
}
for (int i = 1; i < results.size(); i++) {
ArrayList<String> lines = new ArrayList<String>(results);
ArrayList<String> newLines = new ArrayList<String>(results);
for (String line : lines) {
line = line.substring(0, line.length() - 2).trim();
String[] words = line.split(";");
Arrays.sort(words);
StringBuilder sb = new StringBuilder(line.length());
for (String word : words) {
if (word.isEmpty())
continue;
if (sb.length() > 0) {
sb.append(" ");
}
sb.append(word);
}
String newLine = sb.toString();
newLines.add(newLine);
}
System.out.println("sorted lines:");
for (String line : newLines) {
System.out.println(line);
}
}
答案 0 :(得分:1)
您可以在SQL中按名称检索它。
SELECT firstName, lastName
FROM myTable
ORDER BY lastName ASC;
(或DESC,如果你想要Z到A)
答案 1 :(得分:0)
拆分每一行String@split("; ")
使用Arrays#sort(-)
对其进行排序。
例如:
ArrayList<String> lines = new ArrayList<String>();
//for (int i = 0; i < results.size(); i++){
String in = "Amako; Jun (Shiojiri, JP), Umetsu; Kazushige (Chino, JP),"
+"Tanaya; Hideo (Suwa, JP) ,";
//in = (String)results.get(i);
in = in.substring(0, in.length()-2).trim();
String str[] = in.split("; ");//1
Arrays.sort(str);//2
StringBuffer sb = new StringBuffer();
for(String s:str)
{
System.out.println(s);
sb.append(s);
sb.append("; ");
}
System.out.println(sb.toString().substring(0, sb.toString().length()-2));
lines.add(sb.toString().substring(0, sb.toString().length()-2));
//}
输出:
Amako; Hideo (Suwa, JP) ; Jun (Shiojiri, JP), Umetsu; Kazushige (Chino, JP), Tanaya
对剩下的行做同样的事情..
