Trim (Remove leading and trailing spaces) a string in Java
Given a string, remove all the leading and trailing spaces from the string and return it.
Input : str = " Hello World "
Output : str = "Hello World"
Input : str = " Hey there Joey!!! "
Output : str = "Hey there Joey!!!"
- We can eliminate the leading and trailing spaces of a string in Java with the help of trim().
- trim() method is defined under the String class of java.lang package.
- It does not eliminated the middle spaces of the string.
- By calling the trim() method, a new String object is returned.
- It doesn’t replace the value of String object. Therefore if we want the access to the new String object, we just need to reassign it to the old String or assign it to a new variable.
How it works?
For space character the unicode value is ‘\u0020’. This method checks for this unicode value before and after the string and if it exists then eliminates the spaces(leading and trailing) and returns the string (without leading and trailing spaces).
String str1 =
" Hello World "
String str2 =
" Hey there Joey!!! "
Hey there Joey!!!
Hey there Joey!!!
