字符串数组与字符串之间的互转

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)

/* 
 *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)

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)

<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)

<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>
