Ints join() function | Guava | Java

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() 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

// 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
