[Java][JavaScript]字符串数组与字符串之间的互转

1、Java

 

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

 

            例：view plaincopy to clipboardprint?
/* 
 *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" }, "$#$"));  
  }  
} 
/*
 *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：view plaincopy to clipboardprint?
public SplitDemo() {   
    String s = "AB$#$CD$#$EF";   
    // 在每个空格字符处进行分解。   
    String[] ss = s.split("$#$");      
}  
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:view plaincopy to clipboardprint?
<mce:script type="text/javascript">  
<!--   
var a = new Array("a","b","c");   
a.join("|");   
alert(a);   
// -->  
</mce:script>  
<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：view plaincopy to clipboardprint?
<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>
