从Java字符串中删除前导和尾随空格 [英] Strip Leading and Trailing Spaces From Java String

问题描述

是否有一种方便的方法来从Java字符串中去除任何前导或尾随空格？

类似于：

  String myString =keep this; 
 String stripppedString = myString.strip（）; 
 System.out.println（no spaces：+ strippedString）; 
  

结果：

 无空格：保留此
  

myString.replace（ ，）将替换keep和this之间的空格。

谢谢

  String newString = oldString。修剪（）; 
  

看看 javadocs

Is there a convenience method to strip any leading or trailing spaces from a Java String?

Something like:

String myString = "  keep this  ";
String stripppedString = myString.strip();
System.out.println("no spaces:" + strippedString);

Result:

no spaces:keep this

myString.replace(" ","") would replace the space between keep and this.

Thanks

解决方案

You can try the trim() method.

String newString = oldString.trim();

Take a look at javadocs
