I need some help here

Question

hi, ^-^, i was programming the Caesar encription method, this one:
import java.io.*;
public class lol {
          public static void main (String args[]) throws Exception{
               int seleccion, longi, w, x, y, z;
               String sel, texto, encrip="";
               boolean a=false, b=false;
                                                  System.out.print("Enter a text to encript: ");
                                                  DataInputStream entrada3 = new DataInputStream(System.in);
                                                  texto = entrada3.readLine();
                                                  w=1;
                                                  z=0;
                                                  for(x=1;x==texto.length();x++){
                                                       if(texto.substring(z,w)!= (" ")){
                                                            encrip = encrip + texto.substring(z,w);
                                                            z++;
                                                            w++;
                                                       } else{
                                                            z++;
                                                            w++;
                                                  w=1;
                                                  z=0;
                                                  if ((encrip.length()/2)==0){
                                                       longi = ((encrip.length()^(1/2))+1);
                                                  } else{
                                                       longi = ((encrip.length()^(1/2)));
                                                  String crip[][] = new String[longi][longi];
                                                  texto = "";
                                                  for(x=0;x==longi;x++){
                                                       for(y=0;y==longi;y++){
                                                            crip[y][x]=(encrip.substring(z,w));
                                                            w++;
                                                            z++;
for(x=0;x==longi;x++){
for(Y=0;y==longi;y++){
texto=texto+crip[x][y];
                                                  System.out.println("your ecripted text is: " + texto);
all it do, is: read the text, decompose it, so it dosnt have any spaces, and then, it create an array whit the dimension of the text^1/2 +1 if the text/2==true or the other writted there; then it fills the array (0.0, 1.0, 2.0....,0.1,1.1,...etc), and then it show u the encripted text. My problem here its that the program dosnt go trought any "for bucle" O_o, dunno why.. any help would be apriciated, thx

Answer 1

I'm sorry but my Babel fish isn't working. bucle == loop (like English buckle, I guess)
@OP:
The second part of a for-loops (bucle) is a condition that must be true.
So you should write//for(x=1;x == texto.length(); x++) { //<--  not this
for(x=1;x < texto.length() + 1; x++) {
    // etc
}and the same for the other loops.
Strings are compared using the equals() method, not ==. So//if(texto.substring(z,w)!= (" ")){ // <-- not this
if(!texto.substring(z,w).equals(" ")) {
    // etc
}Exponentiation (potencia) in Java does not use the ^ operator, you have
to use Math.pow()//longi = ((encrip.length()^(1/2))); // <-- not this
longi = Math.round(Math.pow((double)encrip.length(), 0.5));longi will be a long, not an int (but can be used the same way in your
code).
