Split Preserve Tokens2 

Apache Commons Lang 3.0 is a java library with lot of utilities and reusable components. This requires the library commons-lang3-3.0.1.jar to be in classpath. The following example shows using StringUtils.splitPreserveAllTokens() API. It splits the given string into array of tokens using the specified separator characters by preserving all tokens, including empty tokens created by adjacent separators.

package com.bethecoder.tutorials.commons_lang.tests.strings;

import java.util.Arrays;

import org.apache.commons.lang3.StringUtils;

public class SplitPreserveTokensTest2 {

  /**
   @param args
   */
  public static void main(String[] args) {
     
    String [] tokens = StringUtils.splitPreserveAllTokens(null, "abc");
    System.out.println(Arrays.toString(tokens));
    
    tokens = StringUtils.splitPreserveAllTokens("""abc");
    System.out.println(Arrays.toString(tokens));
    
    tokens = StringUtils.splitPreserveAllTokens("be the coder""abc");
    System.out.println(Arrays.toString(tokens));
    
    tokens = StringUtils.splitPreserveAllTokens("abcabbacabbabcabc""c");
    System.out.println(Arrays.toString(tokens));
    
    tokens = StringUtils.splitPreserveAllTokens("ab++cd+ef+g++h""+");
    System.out.println(Arrays.toString(tokens));
  }

}
   

It gives the following output,
null
[]
[, e the , oder]
[ab, abba, abbab, ab, ]
[ab, , cd, ef, g, , h]
