Guava – Shorts.concat()方法及实例

Guava – Shorts.concat()方法及实例

Shorts.concat() 是Guava库中Shorts类的一个方法,用于将多个数组的值连接成一个数组。 例如,concat(new short[] {a, b}, new short[] {}, new short[] {c} 返回数组{a, b, c}。

语法:

public static short[] concat(short[]... arrays)

这里,数组代表零个或多个短数组。

返回值: 一个单一的数组,包含源数组的所有值,按顺序排列。

例子-1。

// Java code to show implementation of
// Guava's Shorts.concat() method
import com.google.common.primitives.Shorts;
import java.util.Arrays;
  
class GFG {
    // Driver's code
    public static void main(String[] args)
    {
        // Creating 2 short arrays
        short[] arr1 = { 1, 2, 3, 4, 5 };
        short[] arr2 = { 6, 2, 7, 0, 8 };
  
        // Using Shorts.concat() method to combine
        // elements from both arrays into a single array
        short[] res = Shorts.concat(arr1, arr2);
  
        // Displaying the single combined array
        System.out.println(Arrays.toString(res));
    }
}

输出:

[1, 2, 3, 4, 5, 6, 2, 7, 0, 8]

例子-2。

// Java code to show implementation of
// Guava's Shorts.concat() method
import com.google.common.primitives.Shorts;
import java.util.Arrays;
  
class GFG {
    // Driver's code
    public static void main(String[] args)
    {
        // Creating 4 short arrays
        short[] arr1 = { 1, 2, 3 };
        short[] arr2 = { 4, 5 };
        short[] arr3 = { 6, 7, 8 };
        short[] arr4 = { 9, 0 };
  
        // Using Shorts.concat() method to combine
        // elements from both arrays into a single array
        short[] res = Shorts.concat(arr1, arr2, arr3, arr4);
  
        // Displaying the single combined array
        System.out.println(Arrays.toString(res));
    }
}

输出:

[1, 2, 3, 4, 5, 6, 7, 8, 9, 0]
