JAVA program for string method trim()

This JAVA program is for string method trim().

String method trim() removes blank spaces from the start and end of a string.

For example  if string str = ‘    hello world   ‘, then str.trim() will remove blank space from start and end of the string thus giving us string as ‘hello world’.

Take input ‘str’.Let us take input str=’    CODEDOST   ‘

str.trim = ‘CODEDOST‘ (blank spaces removed)

import java.util.*;

class trim
{
	public static void main(String args[])
	{
		Scanner sc = new Scanner(System.in);
		System.out.println("Enter the string");
		String str = sc.nextLine();
