int[][] a=new int[2][];
a[0]=new int[2];
a[1]=new int[4];
a[0][0]=1;
a[0][1]=12;
a[1][0]=10;
a[1][1]=3;
a[1][2]=12;
a[1][3]=13;
System.out.println("length-"+a.length);
for (int i = 0; i < a.length; i++) {
for (int k = 0; k < a[i].length; k++) {
System.out.print(a[i][k]+" , ");
}
System.out.println("");
}


}


}
