You made mistake in third loop.
Better looking triple loop is here:
int count = 1000;
for(int i=0; i<ages.length; i++)
for( int j=0; j<ages[i].length; j++)
for ( int k=0; k<ages[i][j].length; k++){
ages[i][j][k]= count;
count++;
System.out.print( "ages["+i+"]["+j+"]["+k+"] "+ ages
[i][j][k] );
}
Everything with loops was fine, instead of "k<ages[i].length" had to
be "k<ages[i][j].length".
