When i input the text it doesnt allow me to put spaces. any ideas why??

import java.util.*;

public class LetterFreq{
public static void main(String[] args){
Letters input1 = new Letters();
Scanner scan = new Scanner(System.in);
String t = " ";
System.out.println("Enter Text Here");
while(t.length() > 0){
t = scan.nextLine();
t = t.toLowerCase();
input1.countLetters(t);
}
input1.printCount();
}
}


public class Letters{
int[] charCount = new int[26];

public void countLetters(String input){
for (int j = 0; j < input.length(); j++){
int hold = 0;
hold = input.charAt(j) - 'a';
if(j >= 0 && j <= 25)
charCount[hold]++;
}
}

public void printCount(){
char letter = 'a';
for (int i = 0; i < 26; i++){
System.out.println(letter + ": " + charCount[i]);
letter++;
}
}

}

You shouldn't need the while look and can just do t = scan.next();

What are your assignment requirements? Also, please edit your code and place in code tags (see my signature below which describes how to do this).
