package com.yiibai;

import java.lang.*;

public class StringDemo {

public static void main(String[] args) {

// string with leading and trailing white space
String str = " This is YiiBai ";

System.out.print("Before trim = ");
System.out.println(".." + str + "..");

// leading and trailing white space removed
System.out.print("After trim = ");
System.out.println(".." + str.trim() + "..");
}
}

Before trim = .. This is YiiBai ..
After trim = ..This is YiiBai..
