Question

我需要将String转换为字符串数组。例如：

String words = "one, two, three, four, five";

进入数组

String words1[];
String words1[0]="one";
       words1[1]="two";
       words1[2]="three";
       words1[3]="four";
       words1[4]="five";

请指导我

Answer 1

我想也许您正在寻找的是：

String words = "one two three four five";
String[] words1 = words.split(" ");

Answer 2

确切答案将按照所有人的建议使用split()功能：

String words = "one, two, three, four, five";
String words1[] = words.split(", ");

Answer 3

试试这个，

 String word = " one, two, three, four, five";        
 String words[] = word.split(",");
 for (int i = 0; i < words.length; i++) {
     System.out.println(words[i]);
 }

如果您需要删除空格，可以通过循环调用.trim();方法。

Answer 4

我在这里编写代码可能对您有所帮助。

import java.util.StringTokenizer;

public class StringTokenizing
{
 public static void main(String s[])
 {
   String Input="hi hello how are you";
 int i=0;
   StringTokenizer Token=new StringTokenizer(Input," ");
   String MyArray[]=new String[Token.countTokens()];
   while(Token.hasMoreElements())
   {
    MyArray[i]=Token.nextToken();
    System.out.println(MyArray[i]);
    i++;
   }
  }
 }
