番石榴的IntsT3。如果目标作为元素出现在数组中的任何位置,contains() 返回 true语法:

public static boolean 
  contains(int[] array, int target)

参数:该方法接受以下参数:

  • 数组:int 值的数组,可能为空。
  • 目标:一个原始 int 值。

返回值:这个方法返回一个布尔值。如果数组[i] ==目标值为 i. 则返回示例 1:

Java 语言(一种计算机语言,尤用于创建网站)

// Java code to show implementation of
// Guava's Ints.contains() 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 = { 5, 4, 3, 2, 1 };

        int target = 3;

        // Using Ints.contains() method to search
        // for an element in the array. The method
        // returns true if element is found, else
        // returns false
        if (Ints.contains(arr, target))
            System.out.println("Target is present"
                               + " in the array");
        else
            System.out.println("Target is not present"
                               + " in the array");
    }
}

Output: 

Target is present in the array
