StringJoiner length() method in Java 8
The length() method of the StringJoiner class in Java 8 is used to get the length of the current value of StringJoiner.
To work with the StringJoiner in Java 8, import the following package:
import java.util.StringJoiner;
The syntax is as follows:
public int length()
First, create a StringJoiner:
StringJoiner strJoin = new StringJoiner(",");
strJoin.add("US");
strJoin.add("India");
strJoin.add("Netherlands");
strJoin.add("Australia");Now, find the length of the StringJoiner i.e. the number of elements in it using the length() method:
strJoin.length());
The following is an example to implement StringJoiner length() method in Java:
Example
import java.util.StringJoiner;
public class Demo {
public static void main(String[] args) {
// StringJoiner
StringJoiner strJoin = new StringJoiner(",");
strJoin.add("US");
strJoin.add("India");
strJoin.add("Netherlands");
strJoin.add("Australia");
System.out.println("Length of the StringJoiner = "+strJoin.length());
System.out.println("StringJoiner = "+strJoin.toString());
}
}Output
Length of the StringJoiner = 30 StringJoiner = US,India,Netherlands,Australia
