Java: If we have one hashmap, each key is one kind of bread name, each value is this bread price. such as {cake - 15, donut -7, cheesecake -15, baguette -17}

now we should print all bread are listed in ascending order by price. Also, if we have same price bread, print listed alphabetically. NO nested loop!no line over 80 columns!

so output: donut: 7

cake: 15

cheesecake: 15

baguette : 17
