Ints类中的concat()函数用于连接作为参数传递的数组。语法如下-
public static int[] concat(int[]... arr)
此处,参数arr为零或多个整数数组。
让我们看一个例子-
import com.google.common.primitives.Ints; import java.util.*; class Demo { public static void main(String[] args) { int[] myArr1 = { 100, 150, 230, 300, 400 }; int[] myArr2 = { 450, 550, 700, 800, 1000 }; System.out.println("Array 1 = "); for(int i=0; i < myArr1.length; i++) { System.out.println(myArr1[i]); } System.out.println("Array 2 = "); for(int i=0; i < myArr2.length; i++) { System.out.println(myArr2[i]); } int[] arr = Ints.concat(myArr1, myArr2); System.out.println("Concatenated arrays = "+Arrays.toString(arr)); } }
输出结果
Array 1 = 100 150 230 300 400 Array 2 = 450 550 700 800 1000 Concatenated arrays = [100, 150, 230, 300, 400, 450, 550, 700, 800, 1000]
