java 如何将三个一维数组拼成一个三维数组？

Answer 1

public class test{
public static void main(String[] args){
int [] arr1 = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; // 假设这是你的坐标(1,2),(3,4),……
int [][] arr2 = new int[arr1.length / 2][2]; // 创建一个行为原数组长度一半，列为2的二维数组
for (int i = 0; i < arr1.length; i++) {
// 遍历原数组，赋值给新数组
arr2[i / 2][i % 2] = arr1[i];
}
for (int i = 0; i < arr2.length; i++ ) {
for (int j = 0; j < arr2[i].length; j++ ) {
System.out.print(arr2[i][j] + " ");
}
System.out.println();
}
}
}
输出
1 2
3 4
5 6
7 8
9 10
