整数 min()函数|番石榴 |Java

Guava的Ints.min()返回数组中存在的最小值。

句法：

public static int min(int... array)

参数：此方法将数组作为参数，该数组是一个非空的int值数组。

返回值：此方法返回数组中存在的值，该值小于或等于数组中的所有其他值。

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

下面的示例说明了 Ints.min() 方法：

示例 1：

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

输出：

Minimum Value is: -5

示例 2：演示 IllegalArgumentException

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

输出：

Exception: java.lang.IllegalArgumentException
