下面這段代碼似乎對我來說工作得很好。
但是,我認爲您需要分割的分隔符只是一個字符。
public static void main(String[] args){
String string = ",alpha,beta,gamma,,delta";
String[] wordsSplit = splitByDelimiter(string, ",");
for(int i=0; i<wordsSplit.length; i++){
System.out.println("-"+wordsSplit[i]+"-");
}
}
public static String[] splitByDelimiter(String fullString, String delimiter){
// Calculate number of words
int index = 0;
int[] delimiterIndices = new int[fullString.length()];
int wordCount = 0;
do{
if(delimiter.equals(fullString.charAt(index)+"")){
delimiterIndices[wordCount++] = index;
}
index++;
} while(index < fullString.length());
// Correction for strings not ending in a delimiter
if(!fullString.endsWith(delimiter)){
delimiterIndices[wordCount++] = fullString.length();
}
// Now create the words array
String words[] = new String[wordCount];
int startIndex = 0;
int endIndex = 0;
for(int i=0; i<wordCount; i++){
endIndex = delimiterIndices[i];
words[i] = fullString.substring(startIndex, endIndex);
startIndex = endIndex+1;
}
return words;
}
替代的解決方案:
public static ArrayList splitByDelimiter(String fullString, String delimiter){
fullString += delimiter; //
ArrayList words = new ArrayList();
int startIndex = 0;
int endIndex = fullString.indexOf(delimiter); //returns first occurence
do{
words.add(fullString.substring(startIndex, endIndex));
startIndex = endIndex+1;
endIndex = fullString.indexOf(delimiter, startIndex);
} while(endIndex != -1);
return words;
}
很抱歉,但不只是用java的舊版本,而嘗試更新它(取決於其大小) – ScriptKiddy
