介绍Java Fencepost / While循环Conitional测试

I've been trying to answer this problem all night, but I think my brain is just too fried from my midterms to answer it correctly. So the question exactly is [quoted]: Write a method highLow that accepts an integer as a parameter and returns whether or not the number has alternating "high" and "low" digits. 0 through 4 are "low" digits and 5 through 9 are "high" digits. Your method should return true if the number passed alternates between "high" and "low" digits, and false if not. You may assume the number passed is positive. If the number passed consists of a single digit, your method should return true.I've been trying to answer this problem all nig
