Chars.min() is a method of Chars 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 char value in the specified array.
Syntax :
public static char min(char... array)
Parameters: This method takes a mandatory parameter array which is a nonempty array of char values.
Return Value: This method returns a char 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 Chars.min() method  import com.google.common.primitives.Chars;import java.util.Arrays;  class GFG {      // Driver's code    public static void main(String[] args)    {          // Creating a character array        char[] arr = { 'A', 'E', 'I', 'O', 'U' };          // Using Chars.min() method to get the        // minimum value present in the array        System.out.println("Minimum Value is : "                           + Chars.min(arr));    }} |
Output:
Minimum Value is : A
Example 2 :
// Java code to show implementation of// Guava's Chars.min() method  import com.google.common.primitives.Chars;import java.util.Arrays;  class GFG {      // Driver's code    public static void main(String[] args)    {        // Creating a character array        char[] arr = {};          try {            // Using Chars.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 : "                               + Chars.min(arr));        }        catch (Exception e) {            System.out.println(e);        }    }} |
Output:
java.lang.IllegalArgumentException
