在arraylist中找到类似的字符串 [英] Find similar string in arraylist

问题描述

您如何在arraylist中找到类似的字符串并计算重复的字符串

解决方案

一旦您定义了'相似性测试'，这是一个确定if的方法传递的字符串是否相似你可以将这样的方法应用于列表中的字符串对，并在测试通过时递增计数器。

编写测试字符串相似性的方法一项微不足道的任务，很大程度上取决于（如谢尔盖所​​说）你的要求。

示例代码：

 List< string> list =  new  ArrayList< string>（）; 
 list.add（  aaa）; 
 list.add（  bbb）; 
 list.add（  aaa）; 
 
设置< string> unique =  new  HashSet< string>（list）; 
  for （ String  key：unique）{
 System.out.println（ key +  ： + Collections.frequency（list，key））; 
}< / string>< / string>< / string>< / string>

Hi how do I find similiar string in an arraylist and count the duplicated strings

解决方案

Once you defined a 'similitude test', that is a method establishing if the passed strings are similar or not you could apply such a method to the string pairs in your list and increment the counter whenever the test is passed.
Writing a method testing the similarity of the strings it is not a trivial task and heavily depends (as noted by Sergey) on your requirements.

sample code:

List<string> list = new ArrayList<string>();
list.add("aaa");
list.add("bbb");
list.add("aaa");

Set<string> unique = new HashSet<string>(list);
for (String key : unique) {
    System.out.println(key + ": " + Collections.frequency(list, key));
}</string></string></string></string>
