java 字符串 转数组 Java – How to convert String into Array

String contains a long tail of character with special  character and normal character. Converting string into Array can be done by  split() method of java and StringTokenizer() method of StringTokenizer class.
  We will give you both method of convert String into array.
  Split  method is newer method in java, StringTokenizer was old method and previous it  was used.

 

 

import java.util.StringTokenizer;public class StringToArray {    public static void main(String[] args) {        String str2array="Converting java String into Array";        //1. First method with split()         // split(String Delimiter)        String[] arr=str2array.split(" ");        System.out.println("Array :"+arr.length);        for(int i=0;i<arr.length;i++)        {            System.out.println("array"+i+"  :"+arr[i]);        }        //2. Second Method of StringTokenizer        // StringTokenizer(String str, String delimiter)        StringTokenizer stArr=new StringTokenizer(str2array," ");        while(stArr.hasMoreTokens())        {            System.out.println("Token  :"+stArr.nextToken());        }    }}

 

Output

 

Array :5 array0 :Converting array1 :java array2 :String array3 :into array4 :Array Token :Converting Token :java Token :String Token :into Token :Array
