英文:
Write the code to process the list of words and trim any spaces out of the words
问题
这段代码应该检查字符串数组中的每个字符串，看看单词之间是否有空格。以下是一个示例：{“every”，“near ing”，“checking”，“food”，“stand”，“value”}。它应该被更改为：{“every”，“nearing”，“checking”，“food”，“stand”，“value”}。以下是迄今为止的我的代码：
package space;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class spacefinder {
public static void main (String[] args) {
String[] arr = {"every", "near ing", "checking", "food", "stand", "value"};
Pattern pattern = Pattern.compile("\\s");
for (int i = 0; i < arr.length; i++) {
Matcher matcher = pattern.matcher(arr[i]);
arr[i] = matcher.replaceAll("");
}
}
}
这段代码会产生一个错误，而且我看到的每个教程都没有使用字符串数组，比如我这种情况下的 String[] Arr，他们只使用了一个常规的 String = 语句。
英文:
This code is supposed to check through an array of strings and see if there is a space between a word. Here is an example: {“every”, “near ing”, “ checking”, “food “, “stand”, “value “}. It should be changed to hold: {“every”, “nearing”, “checking”, “food”, “stand”, “value”}. Here is my code so far:
package space;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class spacefinder {
public static void main (String[] args) {
String[] arr = {"every", "near ing", "checking", "food", "stand", "value"};
Pattern pattern = Pattern.compile("\\arr");
Matcher matcher = pattern.matcher(arr);
boolean found = matcher.find();
}
}
This code results in an error, and every tutorial I see does not use a string array, such as the String[] Arr in my case, they only use a regular String = statement.

得分: 1
你可以尝试类似这样的代码：
for(int i = 0; i < arr.length; i++) {
arr[i] = arr[i].replace(" ", "");
}
英文:
You can try something like this:
for(int i = 0; i<arr.length; i++) {
arr[i] = arr[i].replace(" ", "");
}

也许这会起作用
public static String[] removeSpace(String[] ans) {
for(String s:ans){
while(s.contains(" ")){
s = s.split(" ")[0] + s.split(" ")[1];
}
}
return ans;
}
英文:
maby this wil work
public static String[] removeSpace(String[] ans) {
for(String s:ans){
while(s.contains(" ")){
s = s.split(" ")[0] + s.split(" ")[1];
}
}
return ans;
}
