【JAVA】创建一维数组+创建二维数组

public static void main(String[] args) {
        int[] One1 = new int[5];
        int[] One2 = {1,2,3,4,5};
        int[] One3 = new int [] {1,2,3,4,5};
        int[][] Two1={{1,2,3},{4,5,6}};
        int[][] Two2 = new int[2][3];
        int[][] Tow3 = new int[5][];
        for(int i=0; i<Tow3.length;i++){
            Tow3[i]=new int[i+1];
            for(int j=0; j<Tow3[i].length;j++)
                Tow3[i][j]= i+j;
        }

    }
