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

 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>
