  • Last Updated : 15 Nov, 2018

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 paramters:

  • 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 returnst a string containing the supplied int values separated by separator.



Below examples illustrate the Ints.join() method:

Example 1:




// Java code to show implementation of
// Guava's Ints.join() method
  
import 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 code to show implementation of
// Guava's Ints.join() method
  
import 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
