Can not figure out Javas strings? -


i student @ moment still learning. picked vb pretty quick , simple java on other hand pretty confused on.

the assignment have been given time has me confused "write method determine number of positions 2 strings differ by. example,"peace" , "piece" differ in 2 positions. method declared int compare(string word1, string word2); if strings identical, method returns 0. returns -1 if 2 strings have different lengths."

additional "write main method test method. main method should tell how many, positions strings differ, or identical, or if different lengths, state lengths. strings console. far @ , looking break down in dumdum terms if can don't need solution understanding it.

package arraysandstrings; import java.util.scanner;  public class differstrings {     public static void main (string agrs[]){         scanner scanner = new scanner (system.in);         system.out.print("enter word");         string word1;         string word2;         word1 = scanner.next();         system.out.print("enter word");         word2 = scanner.next();         int count = 0;         int length = word1.length();          for(int x = 0; x >= length; x = x+1) {             if (word1.charat(x) == word2.charat(x)) {                 count = count + 1;                 system.out.print (count);             }         }     } }

additional question

   package arraysandstrings;    import java.util.scanner;   public class differstrings {  public static void main (string agrs[]){  scanner scanner = new scanner (system.in);  system.out.println("enter word");  string word1 = scanner.next();  system.out.println("enter word"); string word2 = scanner.next(); int count = 0; int word1length = word1.length(); int word2length = word2.length();  if (word1length != word2length) {       system.out.println ("words diffrent length");       system.out.println (word1 + "has" + word1.length() + " chars");       system.out.println (word2 + "has" + word2.length() + " chars"); }  for(int x = 0; x < word1length; x = x+1) {         if (word1.charat(x) != word2.charat(x)) {         count = count + 1;        }}}   system.out.println (count+" different chars");

}

after implementing knowledge iv gained responses have ran in problem last line:

 system.out.println (count+" different chars");

it says error expected worked before added next part of assignment this:

   if (word1length != word2length) {       system.out.println ("words diffrent length");       system.out.println (word1 + "has" + word1.length() + " chars");       system.out.println (word2 + "has" + word2.length() + " chars"); } 

for(int x = 0; x >= length; x = x+1) {

you mean

for(int x = 0; x < length; x = x+1) {

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
