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
