How to simplify Java array

Question

Mynumber[][] b=new Mynumber[2][2];

b[0][0]=new Mynumber();
b[1][0]=new Mynumber();
b[0][1]=new Mynumber();
b[1][1]=new Mynumber();

b[0][0].n=50;
b[0][1].n=60;
b[1][0].n=70;
b[1][1].n=80;

Such as

int[][] a={{10,20},{30,40}};

Answer 1

int num = 50;

for (int i = 0; i < 2; i++)
{
for (int j = 0; j < 2; j++)
{
b[i][j] = new Mynumber();
b[i][j].n = num;
num+=10;
}
}

This should be purrrrfect.

Answer 2

Mynumer [][] b=
{{new Mynumber (),new Mynumber ()},
{new Mynumber (),new Mynumber ()}};
should work
