Splitter example

Split with delimiter

@Test
public void split_string_to_list_using_delimiter () {
    
    List<String> oakTrees =  
        Splitter.on(',')
            .trimResults()
            .omitEmptyStrings()
            .splitToList("Granit Oak, Bartek, Gernikako Arbola, "
                    + "Queen Elizabeth Oak, Kongeegen (the King Oak), "
                    + "ChĂȘne chapelle, Poltava Oak,,,");
    
    assertEquals(7, oakTrees.size());
}

Split with Charmatchers

@Test
public void split_string_to_list_using_charmatchers () {

    List<String> abcs123s = Splitter.on(CharMatcher.anyOf(";,.)"))
            .trimResults()
            .omitEmptyStrings()
            .splitToList("a,b;c.d,e.f),g,h.i;j.1,2.3;4.5,6;7.8,9;0");
    
    assertEquals(20, abcs123s.size());    
}

Split with Regular expression

@Test
public void split_string_using_regular_expresion () {
    
    List<String> splitOnLetter = Splitter
            .onPattern("a|b")
            .splitToList("12312a31231b23123");

    assertEquals(3, splitOnLetter.size());
}

Split on fix length

@Test
public void split_string_to_list_using_fix_length () {
    
    List<String> digits = Splitter
            .fixedLength(1)
            .splitToList("1234567890");
    
    assertEquals(10, digits.size());
}

Split string to map

@Test
public void split_string_to_map () {
    
    String str = "firstName:John , lastName:Doe, age:56, address:1234 Elm Street";
    
    Map<String, String> demographics = Splitter.on(",")
          .trimResults()
          .withKeyValueSeparator(":")
          .split(str);
    
    assertEquals(4, demographics.size());
}
