Introduction
In this demo I have used NetBeans IDE 8.2 for debugging purpose. But you can use any java programming language compiler as per your availability..
Write a Java program to trim a string(remove whitespaces)
public class Javaexcercise {
public static void main(String[] args)
{
String str = " TECHSTUDY ";
// Trim the whitespace from the front and back of the String.
String new_str = str.trim();
// Display the strings for comparison.
System.out.println("Original String: " + str);
System.out.println("New String: " + new_str);
}
}Result
