import java.util.Scanner;
public class TwoDotSevenNumbaTwo {
public static void main(String[] args) {
// TODO Auto-generated method stub
String input;
int num1, num2, leng;
char word;
Scanner inputscan = new Scanner(System.in);
System.out.println("Give me some love baby");
input = inputscan.nextLine();
leng = input.length();
num1 = 0;
num2 = 1;
while (num1 < leng) {
input = input.replaceAll(" ", "<space>");
System.out.println(input.charAt(num1));
num1++;
}
}
}
I can't seem to figure out how to get the <space>
on a single line. I know I can't do it because it is a char but I can't find a way around it.
You could do
for(int i = 0; i < leng; ++i) {
char x = input.charAt(i);
System.out.println(x == ' ' ? "<space>" : x);
}
Once you've stored the input as a String, you can write:
// Break the string into individual chars
for (char c: input.toCharArray()) {
if (c == ' ') { // If the char is a space...
System.out.println("<space>");
}
else { // Otherwise...
System.out.println(c);
}
}
Regex powa:
yourText.replaceAll(".", "$0\n").replaceAll(" ","<space>");
Explanation:
First replaceAll takes every charachter ( .
= any character) and replaces it with the same character ( $0
= matched text) followed by a newline \\n
, thusly every character is on separate line.
Second replaceAll just replaces every acctual space with the word "<space>"
