JAVA拆分字符串形成整形数

Question

拆分字符串，形成整型数的二维数组，并打印输出：
String str="0x12,0x34,0x56/0xaa,0x1b,0xcc/0x7e,0x5b";

Answer 1

public class Main {
    public static void main(String[] args) {
        String str = "0x12,0x34,0x56/0xaa,0x1b,0xcc/0x7e,0x5b";
        String[] arr1 = str.split("/");
        String[][] arr = new String[arr1.length][];
        for (int i = 0; i < arr1.length; i++) {
            arr[i] = arr1[i].split(",");
        }
        int[][] result = new int[arr.length][];
        for (int i = 0; i < arr.length; i++) {
            result[i] = new int[arr[i].length];
            for (int j = 0; j < arr[i].length; j++) {
                result[i][j] = Integer.decode(arr[i][j]);
            }
        }
        for (int i = 0; i < result.length; i++) {
            for (int j = 0; j < result[i].length; j++)
                System.out.print(result[i][j] + " ");
            System.out.println();
        }
    }
}
