Original article: http://blog.csdn.net/szwangdf/article/details/4177104

 

1. Java

1-1. String Array => string: stringutils: Join (object [] array, string separator)

Example:

 
/** Join strings using separator >>> AB $ # $ CD $ # $ EF */import Org. apache. commons. lang. stringutils; public class stringutilstrial {public static void main (string [] ARGs) {// join all strings in the array into a single string, // separated by $ # $ system. out. println (stringutils. join (New String [] {"AB", "cd", "Ef"}, "$ # $ "));}}
 

1-2. String => string array: String: Split (string separator) Example:

 
Public splitdemo () {string S = "AB $ # $ CD $ # $ EF"; // separate each space character. String [] Ss = S. Split ("$ # $ ");}
 

 

2. Javascript

2-1. String Array => string: array: Join (string separator)

Example:

View plain

1. <MCE: Script Type ="Text/JavaScript">
2. <! --
3. VaRA =NewArray ("","B","C");
4. A. Join ("|");
5. Alert ();
6. // -->
7. </MCE: SCRIPT>

 

2-2. String => string array: String: Split (string separator), string: Split (string separator, int length)

Example:

View plain

2. <MCE: Script Type ="Text/JavaScript">
4. <! --
6. VaRSTR ="1234";
8. VaRStr1 ="Basketball, volleyball, and table tennis";
10. VaRArr = Str. Split ("");// Separate all
12. VaRArr1 = str1.split (",");// Split by comma
14. VaRArr2 = str1.split (",", 2 );// Split by comma and retain two segments
16. // -->
18. </MCE: SCRIPT>
