Ints min() function | Guava | Java
  • Last Updated : 15 Nov, 2018

Guava’s Ints.min() returns the least value present in array.

Syntax:

public static int min(int... array)

Parameters: This method takes the array as parameter which is a nonempty array of int values.

Return Value: This method returns the value present in array that is lesser than or equal to every other value in the array.

Exceptions: The method throws IllegalArgumentException if array is empty.



Below examples illustrates the Ints.min() method:

Example 1:




// Java code to show implementation of
// Guava's Ints.min() 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, 10, 0, -5, 15 };
  
        // Using Ints.min() method to get the
        // minimum value present in the array
        System.out.println("Minimum Value is: "
                           + Ints.min(arr));
    }
}
Output:
Minimum Value is: -5

Example 2: To demonstrate IllegalArgumentException




// Java code to show implementation of
// Guava's Ints.min() method
  
import com.google.common.primitives.Ints;
import java.util.Arrays;
  
class GFG {
  
    // Driver's code
    public static void main(String[] args)
    {
  
        try {
            // Creating an integer array
            int[] arr = {};
  
            // Using Ints.min() method to get the
            // minimum value present in the array
            // This should raise "IllegalArgumentException"
            // as the array is empty
            System.out.println("Minimum Value is : "
                               + Ints.min(arr));
        }
        catch (Exception e) {
            System.out.println("Exception: " + e);
        }
    }
}
Output:
Exception: java.lang.IllegalArgumentException
