Random numbers in 2d array java-CodePudding

I hava a problem, when I tried to enter random numbers (0 and 1) in a 2D array, that when I enter a number of rows and columns, the output will appear Exception in thread.

"main":java.lang.ArrayIndexOutOfBoundsException: Index 3 out of bounds    
for length 3
at Test.main


    public static void main(String[] args) {
    Random r = new Random();
    Scanner input = new Scanner(System.in);

    System.out.println("Enter number of rows");
    int row = input.nextInt();
    System.out.println("Enter number of columns");
    int column = input.nextInt();

    int matrix [][] = new int[row][column];

    for(int i = 0; i< matrix.length;i  ){
        for (int j = 0; i< matrix.length;j  ) {

            matrix[i][j]  = r.nextInt(2);
            System.out.print(matrix[i][j]  " ");
            }
        System.out.println();
    }
    }

        int matrix [][] = new int[row][column];

        for(int i = 0; i< matrix.length;i  ){
