Guava Ints min() 函数

Guava的 Ints .min() 返回数组中存在的 least 值。

语法:

public static int min(int... array)

参数： 该方法以 array 为参数，是一个非空的int值数组。

返回值： 该方法返回数组中小于或等于数组中其他值的值。

异常情况。 如果数组为空，该方法会抛出IllegalArgumentException。

下面的例子说明了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: 为了证明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
