Guava’s Ints.join() returns a string containing the supplied int values separated by separator.
For example, join(“-“, 1, 2, 3) returns the string “1-2-3”.
Syntax:
public static String
join(String separator, int[] array)
Parameters: This method takes the following parameters:
- separator: The text that should appear between consecutive values in the resulting string (but not at the start or end).
- array: An array of int values.
Return Value: This method returns a string containing the supplied int values separated by separator.
Below examples illustrate the Ints.join() method:
Example 1:
Java
// Java code to show implementation of// Guava's Ints.join() methodimport com.google.common.primitives.Ints;import java.util.Arrays;class GFG { // Driver's code public static void main(String[] args) { // Creating an integer array int[] arr = { 2, 4, 6, 8, 10 }; // Using Ints.join() method to get a // string containing the elements of array // separated by a separator System.out.println(Ints.join(", ", arr)); }} |
Output:
2, 4, 6, 8, 10
Example 2:
Java
// Java code to show implementation of// Guava's Ints.join() methodimport com.google.common.primitives.Ints;import java.util.Arrays;class GFG { // Driver's code public static void main(String[] args) { // Creating an integer array int[] arr = { 3, 5, 7, 9, 11 }; // Using Ints.join() method to get a // string containing the elements of array // separated by a separator System.out.println(Ints.join("-", arr)); }} |
Output:
3-5-7-9-11
