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:
// Java code to show implementation of// Guava's Floats.join() method import com.google.common.primitives.Floats;import java.util.Arrays; class GFG { // Driver's code public static void main(String[] args) { // Creating a float array float[] arr = { 2.3f, 4.2f, 6.2f, 8.6f, 10.5f }; // Using Floats.join() method to get a // string containing the elements of array // separated by a separator System.out.println(Floats.join("#", arr)); }} |
Output:
2.3#4.2#6.2#8.6#10.5
Example 2:
// Java code to show implementation of// Guava's Floats.join() method import com.google.common.primitives.Floats;import java.util.Arrays; class GFG { // Driver's code public static void main(String[] args) { // Creating a float array float[] arr = { 3.2f, 5.4f, 7.6f, 9.1f, 11.2f }; // Using Floats.join() method to get a // string containing the elements of array // separated by a separator System.out.println(Floats.join("*", arr)); }} |
Output:
3.2*5.4*7.6*9.1*11.2
