🔒 Closed Java how to cencor user input and detect special character on a string

[Nero Swallowtail]

guys help! paano po ba ung ganon? ung pag ka nag i input is user sa mismong scanner e napapalitan ng asterisk ung iniinput nya sa mismong scanner? or kahit kapag dun nalang sa mismong compiler, kapag prinint ung inenter na password e magiging asterisk lahat? tsaka kung pano na din gagawa ng User Defined Exception kapag ka my Special character na naka sulat, kahit formatting nalang po ibigay nyo, wala po kase sa handout hehehehe ty

Replace lahat ng asterisk yung input ng user? i.e. userInput = "PHC" then output ay "***".

Im not into java, pero sa pagkaka-alam ko may Console.readPassword() na keyword. Go search for it; 'java scanner input masking'

 

[PHC rem]

try mo nga to
char[] password = console.readPassword("Enter password");
Arrays.fill(password, ' ');

[CODE title="baka makatulong"]public class Test {

public static void main(final String[] args) throws Exception {
ConsoleReader reader = new ConsoleReader();
Character mask = '*';
String line = null;
do {
line = reader.readLine("Enter Password(blank pwd to exit)> ", mask);
System.out.println("Got password: " + line);
} while (line != null && line.length() > 0);
}

}[/CODE]

[Nero Swallowtail]

[XX='PHC rem, c: 1117733, m: 765534'][/XX] diba kase sa c# my Console.Readkey akala ko ung Console.readPassword parang other scanner sa c# e HAHAHA

[XX='Nero Swallowtail, c: 1118452, m: 1752019'][/XX] may mga similarities din kasi yong java at c# minsan nalilito din ako.

JAVA:
set mo lang yung echoCharacter ng jPasswordField ng ganito:
jPasswordField.setEchoChar((char)0) - Makikita mo yung characters sa textfield.
jPasswordField.setEchoChar('\u50cf') - Magiging small squares yung characters sa textfield. Palitan mo lang yung '\u50cf' sa kung anong gusto mong character. Yung * yata ay '\u20cf'. di ko lang sure.
