Java番石榴 |带有示例的 Chars.max() 方法

Chars.max()是 Guava 库中 Chars 类的一个方法,用于查找数组中存在的最大值。该方法返回的值是指定数组中最大的char值

句法:

public static char max(char... array)

参数:此方法采用一个强制参数数组,该数组是一个非空的char值数组。

返回值:此方法返回一个字符值,它是指定数组中的最大值。

异常:如果数组为空,该方法将抛出IllegalArgumentException

下面的程序说明了上述方法的使用:

示例 1:

// Java code to show implementation of
// Guava's Chars.max() 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.max() method to get the
        // maximum value present in the array
        System.out.println("Maximum value is : "
                           + Chars.max(arr));
    }
}
输出:
Maximum value is : U

示例 2:

// Java code to show implementation of
// Guava's Chars.max() 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.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 : "
                               + Chars.max(arr));
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}
输出:
java.lang.IllegalArgumentException
