J2ME中的分割字串逻辑 [英] Split string logic in J2ME

问题描述

我正在开发J2ME应用程序.

I am developing a J2ME application.

我想在"<br>"&处分割以下字符串逗号:

I want to split the following string at "<br>" & comma:

3,toothpaste,2<br>4,toothbrush,3

我该怎么做?

推荐答案

  private String[] split(String original,String separator) {
    Vector nodes = new Vector();
    // Parse nodes into vector
    int index = original.indexOf(separator);
    while(index >= 0) {
        nodes.addElement( original.substring(0, index) );
        original = original.substring(index+separator.length());
        index = original.indexOf(separator);
    }
    // Get the last node
    nodes.addElement( original );

     // Create split string array
    String[] result = new String[ nodes.size() ];
    if( nodes.size() > 0 ) {
        for(int loop = 0; loop < nodes.size(); loop++)
        {
            result[loop] = (String)nodes.elementAt(loop);
            System.out.println(result[loop]);
        }

    }
   return result;
}

上面的方法将让您围绕传递的分隔符分割字符串，就像J2EE的String.split()一样.因此，首先在换行标记上拆分字符串，然后在返回数组的每个偏移量处添加逗号，". 例如

The above method will let you split a string about the passed separator, much like J2EE's String.split(). So first split the string on the line break tag, and then do it at each offset of the returned array for the "," comma. e.g.

 String[] lines = this.split(myString,"<br>");
 for(int i = 0; i < lines.length; i++) 
 {
      String[] splitStr = this.split(lines[i],",");
      System.out.println(splitStr[0] + " " + splitStr[1] + " " + splitStr[2]);     
 }
