How to use Java's string trim() method
The trim() method in Java eliminates leading and trailing whitespaces in a string. Here is how the method is defined:
public String trim()
The method takes no parameters, returns a string, and can be called by any string. However, trim() will not alter the original string; a new trimmed string will be returned instead.
Below is a copy of the original string with its whitespaces removed.
Code
The following code snippet demonstrates the usage of the trim() method:
class Program {public static void main( String args[] ) {String str = " the quick brown fox ";System.out.println("String with whitespaces: " + str);String trimmedStr = str.trim();System.out.println("Trimmed string: " + trimmedStr);}}
