How To Find XOR Value Of Character Of Character Array In Java
Mar 3, 2015What I am trying is find the XOR value between charcters of a String here is my code
public static void main(String[] args) {
System.out.println(grayCode("100"));
}
public static String grayCode(String input){
StringBuilder temp=new StringBuilder();

char current=input.charAt(j);
char xorVal=(char)(previous^current);
temp.append(xorVal);
}
return temp.toString();
}

Swing/AWT/SWT :: How To Update Character Count As User Is Counting
Mar 16, 2014i need a password program that does the following:
- only shows the character count
- toggles between seeing the actual letters and character count in the text field with a button
i don't know how to update the character count as the user is counting.i read the oracle tutorial, and i have a vague idea that i'm supposed to use Document Listener but i'm quite clueless here.for the second part i'm thinking about using white space for the masking character and unmasking the field.
Swing/AWT/SWT :: How To Detect That User Has Typed A Character In JTable Column
May 3, 2015I have a JTable with 5 columns, named: "ID", "Name", "UnitPrice", "Qty", and "Total". Only the columns UnitPrice and Qty are editable by the user. When, for example, for a row in the JTable, the user types 5000 in the UnitPrice column, and types 15 in the Qty column, I would want that when he types the first character in the Qty column (i.e. the character 1) in the Qty column, the Total column displays 5000*1, in other terms 5000.
And when the user types the second character in the Qty column, i.e the character 5, after having typed 1, the Total column should display 5000*15, in other terms 75000. So, to say it concisely, I would want that the Total column refreshes accordingly each time the user types a character in the Qty column. I have tried to use the MouseClicked event of the JTable, but noticed that that does not solve my problem. is there an event I should use to refresh my Total column? Or should I proceed in another fashion?
