Java：我的split方法有问题

我试图创建一个split方法，将从输入文件中读入的一行拆分为返回的字符串数组。问题是，当我通过for循环发送诸如“ho；hi hello”之类的行时，它总是在第一个分隔符或“

”；“

或第一个运算符（如“

”+”

）之后停止。我不确定它为什么这样做，因为我希望它一直迭代到行尾，这意味着在if语句之后，for循环再次迭代，直到

I

我想把它打印出来

This is the string in location 0: ho
This is the string in location 1: ;
This is the string in location 2: hi
This is the string in location 3: hello

目前它只是打印出来的

This is the string in location 0: ho
This is the string in location 1: ;

始终在第一个分隔符或运算符处停止。下面是split方法的代码

private static String[] split(String line) {

    String temp = "";           //var to store each line from input temporarily 
    boolean flag = false;       //var to check if "\" is in the from input
    char[] lineCharArray = line.toCharArray(); //transforms line into array of chars  
    List<String> array = new ArrayList<String>(); //ArrayList to store the split strings temporarily

    for (int i = 0; i<line.length(); i++){
        if (!isDelimiter(lineCharArray[i]) && !isOperator(lineCharArray[i]) && flag==false){
            //System.out.println(lineCharArray[i]);
            temp += lineCharArray[i];
        } else {
            array.add(temp);
            if (isDelimiter(lineCharArray[i])) {
                array.add( String.valueOf(lineCharArray[i])); 
            }
            if (isOperator(lineCharArray[i])) {
                array.add( String.valueOf(lineCharArray[i])); 
            }
        }
    }


    String [] strings = new String[array.size()]; //string that is returned for lexical analysis
    array.toArray( strings );
    for (int i = 0; i<strings.length; i++) {
        System.out.println("This is the string in location " + i + ": " + strings[i]);
    }
    return strings;
}


  private static boolean isDelimiter(char c) {
     char [] delimiters = {':', ';', '}','{', '[',']','(',')',','};
     for (int x=0; x<delimiters.length; x++) {
      if (c == delimiters[x]) return true;      
     }
     return false;
  }

  private static boolean isOperator(char o) {
     char [] operators = {'+', '-', '*','/', '%','<','>','=','!','&','|'};
     for (int x=0; x<operators.length; x++) {
      if (o == operators[x]) return true;      
     }
     return false;
  }

私有静态字符串[]拆分（字符串行）{
字符串temp=”“；//临时存储输入中的每一行的var
boolean flag=false；//检查from输入中是否有“\”的var
char[]lineCharArray=line.toCharArray（）；//将行转换为字符数组
List array=new ArrayList（）；//临时存储拆分字符串的ArrayList
对于（int i=0；i您没有将“”作为分隔符。此外，在将临时值添加到数组后，您需要将其重置为“”。我在此处发现了3个问题

空格不是分隔符，因此预期输出为：

This is the string in location 0: ho
This is the string in location 1: ;
This is the string in location 2: hi hello


在添加任何新字符之前，需要重置
temp
。最好使用
StringBuffer
或
StringBuilder

您还需要将last
temp
添加到数组中

这里我为

循环提供修改后的

：

for (int i = 0; i<line.length(); i++){
    if (!isDelimiter(lineCharArray[i]) && !isOperator(lineCharArray[i]) && flag==false){
        //System.out.println(lineCharArray[i]);
        temp += lineCharArray[i];
    } else {
        array.add(temp);
        // Resetting temp variable.
        temp = "";
        if (isDelimiter(lineCharArray[i])) {
            array.add( String.valueOf(lineCharArray[i]));
        }
        if (isOperator(lineCharArray[i])) {
            array.add( String.valueOf(lineCharArray[i]));
        }
    }
}
// Adding last temp to the array.
array.add(temp);

for（inti=0；我为什么不能在
；
上拆分？谢谢，这真的很有帮助！
for (int i = 0; i<line.length(); i++){
    if (!isDelimiter(lineCharArray[i]) && !isOperator(lineCharArray[i]) && flag==false){
        //System.out.println(lineCharArray[i]);
        temp += lineCharArray[i];
    } else {
        array.add(temp);
        // Resetting temp variable.
        temp = "";
        if (isDelimiter(lineCharArray[i])) {
            array.add( String.valueOf(lineCharArray[i]));
        }
        if (isOperator(lineCharArray[i])) {
            array.add( String.valueOf(lineCharArray[i]));
        }
    }
}
// Adding last temp to the array.
array.add(temp);
