SplitString

This application accepts an arbitrary number of user inputs. Every time this application receives a string, it should add the string to a growing string. Newly added strings should be added to the growing string at the index equal to the newly added string's length. If the newly added string's length is equal to or larger than the growing string, this script should add the new string to the end of the growing string. When this application receives a blank input, this application should stop receiving input and print the growing string to the console. The last string that this program should print is the result of the growing string.

Example: input: 'hello' -> growing string: 'hello' input: 'bear' -> growing string: 'hellbearo' input: 'cow' -> growing string: 'helcowlbearo' input: 'disestablishment' -> growing string: 'helcowlbearodisestablishment' input: '' -> growing string: 'helcowlbearodisestablishment'

output: 'helcowlbearodisestablishment'

And my code is following below:

import java.util.Scanner; public class SplitString { public static void main(String[] args) { Scanner input = new Scanner(System.in); String origenInput = input.nextLine(); StringBuffer origenInput1 = new StringBuffer(origenInput); int length = origenInput.length(); while(true) { String userInput1 = input.nextLine(); StringBuffer UserInput1 = new StringBuffer(userInput1); int length2 = userInput1.length(); if (length <= length2) { origenInput1.append(UserInput1); System.out.println(origenInput1); } else { origenInput1.insert(length2, UserInput1); System.out.println(origenInput1); } } } } 

It works well but it does not work well when user type a blank " anyone can help me there?
