今天去面试了，题目做不出来

[laodabest]

面试失败，叫编一个程序，但在给定时间没编出来，那题目出来分享下，希望高手可以做出来
题目：
编写一程序输出一个由若干单词构成的字符串中的最长单词及其长度，若字符串中有多个单词满足条件须将这些单词全部输出。（注：程序书写要规范）
例：输入字符串为“The indictment said the defendants had collected geographical data indicating thousands of people would be killed in the chemical blast”
输出应为：
最长单词：geographical
单词长度：12

[sTrawman2005]

我觉得这时大家应该鼓励搂主，把搂主题做好即可，动不动就简单啥的，说这有什么用应该好好想想如何改进这样会对大家更好

这道题多做不出来，那还真应该在学学，这样面试1000%会失败。

I expect you'll pass the interview!

嘿嘿，我写的！！！

哪个对啊 我测试了几个都有错误 浮躁那个测试是0啊

真晕阿，看了那么多，都没看到JAVA的精华。
我来写个主要片断：
String[] result = "The indictment said the defendants had collected geographical data indicating thousands of people would be killed in the chemical blast".split("\\s");
for (int x=0; x<result.length; x++)
System.out.println(result[x]);

这是核心，别的代码就自己++++了。

[tjblyy]

我参考了一下上面各位大家的代码,然后自己改了改之后,能够顺利运行并得出正确的结果,特贴在这里,给大家分享一下,借花献佛:
import java.util.Vector;
import java.util.Iterator;
class MaxLenWord
{
private static Vector result=new Vector();
private static String str="";
public static Vector getMaxLenWord(String str)
{
int maxlenWordIndex=0;
String[] strArr=str.split(" ");
for(int i=1;i<strArr.length;i++)
{
if(strArr[i].length()>strArr[maxlenWordIndex].length())
{
maxlenWordIndex=i;
result.clear();
result.add(strArr[i]);

}
else if(strArr[i].length()==strAr[maxlenWordIndex].length())
{
maxlenWordIndex=i;
result.add(strArr[i]);

}
}
for(int i=0;i<result.size();i++)
{
System.out.println("最长长度的单词是："+result.get(i));
}
return result;
}

public static int getMaxLen(Vector v)
{
Iterator it=v.iterator();
int n=0;
if(it.hasNext())
{
n=it.next().toString().length();

}
System.out.println("最大长度是："+n);
return n;
}

public static void main(String []args)
{

str="The indictment said the defendants had collected"
+" geographical data indicating thousands of people"
+" would be killed in the chemical blast";
getMaxLenWord(str);
getMaxLen(getMaxLenWord(str));

}
}

学习学习,尤其是Wasingmon(独自等待)给的代码挺不错的

大家能不能对比下 那个编出来的既正确又简单 而且最重要的是比较规范化

[liligugu]

先用split(" ");取出各个单词,然后在把每个单词执行trim( );在依次比较.length()

[os_rui]

import java.util.*;

public class GetWord{
public static void main(String args[]){
String scString="The indictment said the defendants asdfcdrdztga had collected geographical data indicating thousands of";

StringTokenizer token=new StringTokenizer( scString," ");
Vector result = new Vector();

int lengthTemp=0;
String strTemp="";
int lengthMax=0;

int nextIndex = 0;


while( token.hasMoreTokens() ){

strTemp = token.nextToken();
lengthTemp = strTemp.length();

if( lengthTemp>lengthMax ){//新串替换旧串
result.clear();
lengthMax = lengthTemp;
result.add( 0, strTemp );
continue;
}

if( lengthMax==lengthTemp ){//尾部追加新的字符串
nextIndex = result.size();
result.add( nextIndex, strTemp );
}

}//end while

for(int i=0; i<result.size(); i++ ){
System.out.println( result.elementAt( i ) );
}
}
}

夸张，基础题。。。。。

我觉得不需要在内存中存储字符串,只要记录最长的字符串在输入串(或文件)中的起始指针和长度就行.比较完和,再读输入串(或文件)输出.这样不要开辟太大的内存
