循環通過生成的字符

Question

public class Driver { 

public static void main(String[] args) { 


    int length=0; 
    int MaxNumber=100; 
    StringBuilder password = new StringBuilder(); 





    do { 
     if (PasswordGenerator.matchLength (length)) { 
      break; 
     } 
     length++; // length is randomly picked 
    } while (length < MaxNumber); // or <100 
    System.out.println("The length of the character string is " + length); 


    int index = 0; 
    char f = 0; 


    for (char d = 0; d < 127; d++) { 
     if(PasswordGenerator.matchCharAt(d, index)) { 
      password.append(d); 
      System.out.println("Hey! Char at " + index + " is " + d); 
      d++; 
     } 
    } 



} 
} 

所以，我已經找到了如何找到我通過循環隨機生成的密碼的第一個字符，並想知道我怎麼能提供它通過使用該循環或找到密碼的其他字符另一個。字符遵循循環多長時間，這也是隨機生成的。到PasswordGenerator類的文檔是在這裏。（http://www.technology.heartland.edu/faculty/todds/csci130/assignments/A5_password/doc/index.html）

變化index的價值你試圖找到的角色的位置。如果你想找到所有的人則...

for(int j=0; j < length; j++) 
{ 
     for (char d = 0; d < 127; d++) 
     { 
     if(PasswordGenerator.matchCharAt(d, j)) 
     { 
      password.append(d); 
      System.out.println("Hey! Char at " + index + " is " + d); 

      // No sense in incrementing d and going through all of them 
      // You found it already, break this loop 
      break; 
     } 
    } 
}
