JAVA實現Int多維數組轉一維數組並排序

import java.util.Arrays;
public class HelloWorld {
    public static void main(String []args) {
		int[][] m = {{1,2,3,5},{22,0},{100,200}};
		int[] n;
		int len=0;
		for(int[] element : m ){
			len+=element.length;
		}
		System.out.println("數組長度：" + len);
		n = new int[len];
		int index = 0;
		for(int[] element : m ){
			for(int element2 : element){
				n[index++] = element2;
			}
		}
		Arrays.sort(n);
		System.out.println("return： " + Arrays.toString(n));
    }
}
