[Java][JavaScript]字符串数组与字符串之间的互转（join/split）

1、Java

     1-1、字符串数组=>字符串：StringUtils: join(Object[] array, String separator)

            例：

?

/*

 *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、字符串=>字符串数组：String: split(String separator)            例：

?

public SplitDemo() {  

    String s = "AB$#$CD$#$EF";  

    // 在每个空格字符处进行分解。  

    String[] ss = s.split("$#$");     

}  

 

2、JavaScript

     2-1、字符串数组=>字符串：Array: join(String separator)

          例:

<mce:script type="text/javascript">
<!--
var a = new Array("a","b","c");
a.join("|");
alert(a);
// -->
</mce:script>

 

     2-2、字符串=>字符串数组：String: split(String separator)、String: split(String separator, int length)

          例：

<mce:script type="text/javascript">
<!--
  var str = "一二三四";
  var str1 = "篮球、排球、乒乓球";
  var arr = str.split("");//全部分割
  var arr1 = str1.split("、");//按照顿号分割
  var arr2 = str1.split("、",2);//按照顿号分割,保留两段
// -->
</mce:script>
