我想从第一个字符串中删除空白空间，并使其看起来像第二个字符串。

1)EVANS MD     JOSEPH  J 
2)EVANS MD JOSEPH J 

我的代码：

String finaloriginAutoCompleteText = providerOriginAddress.get(position).getProviderName(); 

Answer 1

String finaloriginAutoCompleteText; 
finaloriginAutoCompleteText = providerOriginAddress.get(position).getProviderName(); 

// trim the string (for leading and ending whitespaces) and then 
// replace all remaining (inner) multiple spaces (\s+) with a single space (" ") 
finaloriginAutoCompleteText = finaloriginAutoCompleteText.trim().replaceAll("\\s+", " ");
