Java Guava | Floats.join() method with Examples
The join() method of Floats Class in the Guava library is used to combine or join all the given float values separated by a separator. These float 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 float values.
For example: join(“-“, 1L, 2L, 3L) returns the string “1-2-3”.
Syntax:
public static String join(String separator, float… array)
Parameters: This method accepts two mandatory parameters:
- separator: which is the floatacter that occurs in between the joined float values.
- array: which is an array of float values that are to be joined.
Return Value: This method returns a string containing all the given float values separated by separator.
Below programs illustrate the use of this method:
Example 1:
import com.google.common.primitives.Floats;
import java.util.Arrays;
class GFG {
public static void main(String[] args)
{
float [] arr = { 2 .3f, 4 .2f, 6 .2f, 8 .6f, 10 .5f };
System.out.println(Floats.join( "#" , arr));
}
}
|
Output:
2.3#4.2#6.2#8.6#10.5
Example 2:
import com.google.common.primitives.Floats;
import java.util.Arrays;
class GFG {
public static void main(String[] args)
{
float [] arr = { 3 .2f, 5 .4f, 7 .6f, 9 .1f, 11 .2f };
System.out.println(Floats.join( "*" , arr));
}
}
|
Output:
3.2*5.4*7.6*9.1*11.2
