在Java中,JDK提供基本类型与String类的转化方法,并且StringBuffer类提供了reverse()方法用于反转字符串,在String对象向int型转为的过程中,如果该字符串不能转换为适当格式时,抛出NumberFormatException异常(注意传入数字是负数时,也会发生转化异常,所以需要绝对值处理),如果转化后的int型变量溢出,就会抛出这个异常。以下给...
publicString reverseWords(String s) { if(s ==null|| s.length() ==0) returns; intindex =0;//the pointer to traverse intlen = s.length(); Stack<String> stack =newStack<String>();//堆栈,先进后出,顺序存入单词,逆序输出 StringBuilder sBuilder =newStringBuilder();//记录每一个单词 char[...

Example2: x = -123, return -321 解题思路:将数字翻转并不难,可以转成String类型翻转,也可以逐位翻转,本题涉及到的主要是边界和溢出问题,使用Long或者BigInteger即可解决。 题目不难: JAVA实现如下: public class Solution { static public int reverse(int x) { if(x==0||x==-2147483648)return 0; bool...
Preliminary results indicate that robust support of service-oriented architecture is available using Java technologies, but efficiently meeting non-functional requirements, such as security and platform-independence, pose design challenges for the developer.Ballantyne, Keith...

Given an input string, reverse the string word by word. For example, Given s = "the sky is blue", return "blue is sky the". Update (2015-02-12): For C programmers: Try to solve it in-place in O(1) space. 2 思路 介绍一种很直接的做法,就是类似于java中String::split函数做的操作...
