爪哇番石榴| Chars.max()方法,带示例

原文:https://www . geesforgeks . org/Java-guava-chars-max-method-with-examples/

Chars.max()番石榴库Chars 类的一种方法,用于查找数组中最大的值。此方法返回的值是指定数组中最大的字符值

*语法:*

public static char max(char... array) 

*参数:*该方法采用强制参数 数组 ,该数组是非空的 char 值数组。

*返回值:*该方法返回一个字符值,该值是指定数组中的最大值。

*异常:*阵为空则法掷IllegalArgumentException

下面的程序说明了上述方法的使用:

*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

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
