客户化排序:其实就是实现java.util.Comparator<Type>接口提供的具体的排序方式,<Type> 是具体要比较对象的类型,他有个compare的方法,如compare(x,y)返回值大于0表示x大于y,以此类推,当我们希望按照自己的想法排序的时候可以重写compare方法。 Map总结:
In this case, compareTo returns the difference of the two character values at position k in the two string -- that is, the value: <blockquote> text/java Kopiraj this.charAt(k)-anotherString.charAt(k) </blockquote> If there is no index position at which they differ, then the ...
