Java String.split()
The method split() splits a String into multiple Strings given the
delimiter that separates them. The returned object is an array which
contains the split Strings.
We can also pass a limit to the number of elements in the returned
array. If we pass 0 as a limit, then the method will behave as if we
didn’t pass any limit, returning an array containing all elements that
can be split using the passed delimiter.
Available Signatures
public String[] split(String regex, int limit)
public String[] split(String regex)Example
@Test
public void whenSplit_thenCorrect() {
String s = "Welcome to Baeldung";
String[] expected1 = new String[] { "Welcome", "to", "Baeldung" };
String[] expected2 = new String[] { "Welcome", "to Baeldung" };
assertArrayEquals(expected1, s.split(" "));
assertArrayEquals(expected2, s.split(" ", 2));
}Throws
-
PatternSyntaxException – if the pattern of the delimiter is invalid.
@Test(expected = PatternSyntaxException.class)
public void whenPassInvalidParameterToSplit_thenPatternSyntaxExceptionThrown() {
String s = "Welcome*to Baeldung";
String[] result = s.split("*");
