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
