public static float max(float... array)

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

Return Value: This method returns a float value that is the maximum 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 Floats.max() method
  
import com.google.common.primitives.Floats;
import java.util.Arrays;
  
class GFG {
  
    // Driver's code
    public static void main(String[] args)
    {
  
        // Creating a float array
        float[] arr = { 2.2f, 4.3f, 6.4f, 10.2f,
                        0f, -5.2f, 15.5f, 7.4f };
  
        // Using Floats.max() method to get the
        // maximum value present in the array
        System.out.println("Maximum value is : "
                           + Floats.max(arr));
    }
}
Output:
Maximum value is : 15.5

Example 2 :




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