Java String Split By Dot Top 3 Favorites

To split a Java string by a dot (.), you can use the split() method of the String class, which takes a regular expression as a parameter.

Here’s an example code snippet:

javascript
String input = "example.string.to.split";
String[] parts = input.split("\\.");

for (String part : parts) {
    System.out.println(part);
}

In this example, the split() method is called on the input string with the regular expression "\\" (which escapes the dot character so that it is treated as a literal dot) followed by the dot character itself. The method returns an array of strings containing the parts of the input string that were separated by dots.

The output of the code above will be:

vbnet
example
string
to
split

Each part of the input string is printed on a separate line.

The split() method in Java is used to split a string into an array of substrings based on a specified delimiter.

Here is the syntax of the split() method:

scss
public String[] split(String regex)

The regex parameter specifies the regular expression (or a plain string, which will be treated as a literal) that is used as the delimiter to split the string.

Here’s an example of using the split() method to split a string into an array:

rust
String str = "apple,banana,orange";
String[] arrOfStr = str.split(",");

for (String s : arrOfStr) {
    System.out.println(s);
}

Output:

apple
banana
orange

In this example, we first create a string str that contains three fruits separated by commas. Then we call the split() method on str and pass in the delimiter , to split the string into an array of substrings. Finally, we iterate over the array and print each substring.

It is true that in Java, the dot (“.”) character has a special meaning and is used to access the members of an object, such as methods or properties. Therefore, if you want to split a string using the dot character as a separator, you need to escape it using a backslash (“”) character.

For example, if you have the following string:

javascript
String myString = "foo.bar";

And you want to split it using the dot character as a separator, you can do it as follows:

javascript
String[] myArray = myString.split("\\.");

In this case, the backslash character is used to escape the dot character, so that it is treated as a regular character and not as a special character with a different meaning.

Note that if you use a single backslash, you will get a compilation error, since the backslash character is also a special character in Java, used to represent escape sequences in string literals. Therefore, you need to escape the backslash itself, by using two backslashes in a row.
