Java Guava | Longs.min() method with Examples

Longs.min() is a method of Longs Class in Guava library which is used to find the least value present in an array. The value returned by this method is the smallest long value in the specified array.

Syntax :

public static long min(long... array)

Parameters: This method takes a mandatory parameter array which is a nonempty array of long values.

Return Value: This method returns a long value that is the minimum value in the specified array.

Exceptions: The method throws IllegalArgumentException if the array is empty.

Below programs illustrate the use of the above method:

Example 1 :

// Java code to show implementation of 
// Guava's Longs.min() method 
  
import com.google.common.primitives.Longs; 
import java.util.Arrays; 
  
class GFG { 
  
    // Driver's code 
    public static void main(String[] args) 
    { 
  
        // Creating a long array 
        long[] arr = { 2, 4, 6, 10, 0, -5, 15 }; 
  
        // Using Longs.min() method to get the 
        // minimum value present in the array 
        System.out.println("Minimum Value is : "
                           + Longs.min(arr)); 
    } 
} 

Output:

Minimum Value is : -5

Example 2 :

// Java code to show implementation of 
// Guava's Longs.min() method 
  
import com.google.common.primitives.Longs; 
import java.util.Arrays; 
  
class GFG { 
  
    // Driver's code 
    public static void main(String[] args) 
    { 
  
        // Creating a long array 
        long[] arr = {}; 
  
        try { 
            // Using Longs.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 : "
                               + Longs.min(arr)); 
        } 
        catch (Exception e) { 
            System.out.println(e); 
        } 
    } 
} 

Output:

java.lang.IllegalArgumentException
