}|code-block|syntax|javascript|1705174|既然您知道需要大写的单词，为什么还要从文件中获取字符串并将其大写。|1705175|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Change your for loop such as 

<pre><code>for(int i = 0;i &lt;= Alice.size();i++) 
{ 
 if(Alice.get(i).contains(word))
 {
 System.out.println(word.toupperCase());

 count++;

 else
 {
 System.out.println(Alice.get(i));
 }
}
</code></pre>

While you know the word which need to be capitalized, why do get the string from the file and capitalize it.

blocks|key|1449700|text|下面是一个在字符串中大写单词的方法：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1449701|private+static+String+capWord(String+s,+String+w)+{
++++int+k+=+s.indexOf(w);
++++if+(k+<+0)

++++return+s.substring(0,+k)+%2B+w.toUpper()+%2B+s.substring(k+%2B+w.length());
}|code-block|syntax|javascript|1449702|在这里使用它：|1449703|System.out.println(capWord(Alice.get(i),+word));|1449704|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

Here's a method to upcase the word within a string:

<pre><code>private static String capWord(String s, String w) {
 int k = s.indexOf(w);
 if (k &lt; 0)
 return s;
 return s.substring(0, k) + w.toUpper() + s.substring(k + w.length());
}
</code></pre>

Use it here:

<pre><code>System.out.println(capWord(Alice.get(i), word));
</code></pre>

blocks|key|5490540|text|首先，您应该将读取循环更改为：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5490541|while(scan.hasNext()){
++++Alice.add(scan.next());
}|code-block|syntax|javascript|5490542|使用next而不是nextLine读取下一个单词，而不是下一行。|offset|length|style|CODE|5490543|但是，如果要保留换行符，还可以执行以下操作：|5490544|while(scan.hasNextLine()){
++++line+=+scan.nextLine();

++++for+(String+w+:+line.split("+"))
++++++++Alice.add(w);
}|5490545|现在，在搜索单词时，可以使用equals方法查找确切的单词，如果要忽略单词大小写，则使用equalsIgnoreCase。下面是它使用equals时的样子|5490546|for(String+w+:+Alice){
++++if(w.equals(word))+{
++++++++System.out.print(w.toUpperCase());
++++++++count%2B%2B;++++++++
++++}+else
++++++++System.out.print(w);|5490547|此外，您可以避免中间列表，并在阅读时处理行。如下所示：|5490548|while(scan.hasNextLine()){
++++line+=+scan.nextLine();

++++for+(String+w+:+line.split("+"))
++++++++if(w.equals(word))+{
++++++++++++System.out.print(w.toUpperCase());
++++++++++++count%2B%2B;++++++++
++++++++}+else
++++++++++++System.out.print(w);
}|5490549|编辑：我没有考虑到行中的最后一个单词可能是您要查找的单词；在这种情况下，因为是最后一个单词，所以它将包括换行符("\n")，因此它不会与w.equals(word)匹配。为了解决这个问题，您可以使用matches方法代替equals。matches采用正则表达式，因此您可以将示例中的if表达式替换为：|BOLD|5490550|if+(w.matches(word+%2B+"\s*")){
++++...
}|5490551|\s是一个预定义的正则表达式匹配组，它将匹配任何空格，包括\n，*用于匹配其中的0个或更多空格。|5490552|entityMap^0|0|0|2|4|9|8|0|0|0|E|6|18|G|1V|6|0|0|0|0|0|3|1W|E|2R|7|32|6|39|7|0|0|0|2|T|2|W|1|0^^$0|@$1|2|3|4|5|6|7|17|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|18|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|19|8|@$I|1A|J|1B|K|L]|$I|1C|J|1D|K|L]]|9|@]|A|$]]|$1|M|3|N|5|6|7|1E|8|@]|9|@]|A|$]]|$1|O|3|P|5|D|7|1F|8|@]|9|@]|A|$E|F]]|$1|Q|3|R|5|6|7|1G|8|@$I|1H|J|1I|K|L]|$I|1J|J|1K|K|L]|$I|1L|J|1M|K|L]]|9|@]|A|$]]|$1|S|3|T|5|D|7|1N|8|@]|9|@]|A|$E|F]]|$1|U|3|V|5|6|7|1O|8|@]|9|@]|A|$]]|$1|W|3|X|5|D|7|1P|8|@]|9|@]|A|$E|F]]|$1|Y|3|Z|5|6|7|1Q|8|@$I|1R|J|1S|K|10]|$I|1T|J|1U|K|L]|$I|1V|J|1W|K|L]|$I|1X|J|1Y|K|L]|$I|1Z|J|20|K|L]]|9|@]|A|$]]|$1|11|3|12|5|D|7|21|8|@]|9|@]|A|$E|F]]|$1|13|3|14|5|6|7|22|8|@$I|23|J|24|K|L]|$I|25|J|26|K|L]|$I|27|J|28|K|L]]|9|@]|A|$]]|$1|15|3|-4|5|6|7|29|8|@]|9|@]|A|$]]]|16|$]]

First, you should change the reading loop to this:

<pre><code>while(scan.hasNext()){
 Alice.add(scan.next());
}
</code></pre>

Using <code>next</code> instead of <code>nextLine</code> reads the next word, instead of the next line.

However, if you want to preserve the line breaks, you could also do:

<pre><code>while(scan.hasNextLine()){
 line = scan.nextLine();

 for (String w : line.split(" "))
 Alice.add(w);
}
</code></pre>

Now when searching for the word, you can use the <code>equals</code> method to find the exact word, or <code>equalsIgnoreCase</code> if you want to ignore the word case. Here is how it would look with <code>equals</code>:

<pre><code>for(String w : Alice){
 if(w.equals(word)) {
 System.out.print(w.toUpperCase());
 count++; 
 } else
 System.out.print(w);
</code></pre>

Also, you could avoid the intermediate List and work on the line as you read it. Something like this:

<pre><code>while(scan.hasNextLine()){
 line = scan.nextLine();

 for (String w : line.split(" "))
 if(w.equals(word)) {
 System.out.print(w.toUpperCase());
 count++; 
 } else
 System.out.print(w);
}
</code></pre>

EDIT: I didn't take into account that the last word on the line may be the word you are looking for; in that case, since is the last word, it will include the line break ("\n"), hence it won't match to <code>w.equals(word)</code>. For tackling this problem down, you can use the <code>matches</code> method instead of <code>equals</code>. <code>matches</code> takes a regular expresion, so you could replace the if expression in the examples for:

<pre><code>if (w.matches(word + "\s*")){
 ...
}
</code></pre>

The <code>\s</code> is a predefined regex match group that will match any whitespace, including <code>\n</code>, and the <code>*</code> is for matching 0 or more of this.

Right what i need it to do is to capitalize the searched for word from each line, so I already have `

<pre><code> File myFile = new File("AliceInWonderland.txt");
 Scanner scan = new Scanner(myFile);
 Scanner uInput = new Scanner(System.in);
 String word;
 int count = 0;

 ArrayList&lt;String&gt; Alice = new ArrayList&lt;String&gt;();

 System.out.println("Select the word that you would like to search for, from the book of alice and wonderland: ");
 word = uInput.next();


 while(scan.hasNext()){
 Alice.add(scan.nextLine());
 }

 for(int i = 0;i &lt;= Alice.size();i++){
 if(Alice.get(i).contains(word)){
 System.out.println(Alice.get(i));
 count++;
 }
 else{
 System.out.println(Alice.get(i));
 }
 }` 
</code></pre>

I could write <code>System.out.println(Alice.get(i).ToUpper);</code> but this would capitalize all lines with searched for word in it and all i want to do is highlight the searched for words
