The join() method of Chars Class in the Guava library is used to combine or join all the given char values separated by a separator. These char values are passed a parameter to this method. This method also takes the separator as the parameter. This method returns a String which is the result of join operation on the specified char values.
For example: join(“-“, 1L, 2L, 3L) returns the string “1-2-3”.
Syntax:
public static String join(String separator, char… array)
Parameters: This method accepts two mandatory parameters:
- separator: which is the character that occurs in between the joined char values.
- array: which is an array of char values that are to be joined.
Return Value: This method returns a string containing all the given char values separated by separator.
Below programs illustrate the use of this method:
Example 1:
import com.google.common.primitives.Chars;
import java.util.Arrays;
class GFG {
public static void main(String[] args)
{
char [] arr = { 'a' , 'b' , 'c' , 'd' , 'e' };
System.out.println(Chars.join( "#" , arr));
}
}

Example 2:
import com.google.common.primitives.Chars;
import java.util.Arrays;
class GFG {
public static void main(String[] args)
{
char [] arr = { 'G' , 'E' , 'E' , 'K' , 'S' };
System.out.println(Chars.join( "*" , arr));
}
