java竖线分割_用竖线字符（“ |”）分割字符串

使用Pattern.quote()

String[] value_split = rat_values.split(Pattern.quote("|"));

//System.out.println(Arrays.toString(rat_values.split(Pattern.quote("|")))); //(FOR GETTING OUTPUT)

使用转义符(用于元字符)

String[] value_split = rat_values.split("\\|");

//System.out.println(Arrays.toString(rat_values.split("\\|"))); //(FOR GETTING OUTPUT)

使用StringTokenizer(避免正则表达式问题)

public static String[] splitUsingTokenizer(String Subject, String Delimiters)

{

StringTokenizer StrTkn = new StringTokenizer(Subject, Delimiters);

ArrayList ArrLis = new ArrayList(Subject.length());

while(StrTkn.hasMoreTokens())

{

ArrLis.add(StrTkn.nextToken());

}

return ArrLis.toArray(new String[0]);

}

使用Pattern类(java.util.regex.Pattern)

Arrays.asList(Pattern.compile("\\|").split(rat_values))

//System.out.println(Arrays.asList(Pattern.compile("\\|").split(rat_values))); //(FOR GETTING OUTPUT)

输出量

[Food 1 ,  Service 3 ,  Atmosphere 3 ,  Value for money 1 ]
