import java.io.Console;
public class NewConsole {
public static void main(String[] args) {

Console c = System.console(); // #1: get a Console
char[] pw;

pw = c.readPassword("%s", "pw: "); // #2: return a char[]
for(char ch: pw)

c.format("%c ", ch); // #3: format output
c.format("\n");
MyUtility mu = new MyUtility();

while(true) {
name = c.readLine("%s", "input?: "); // #4: return a String
c.format("output: %s \n", mu.doStuff(name));
}
}
}
class MyUtility { // #5: class to test
String doStuff(String arg1) {
// stub code
return "result is " + arg1;
}
}  
 

Here at line # 4 variable name is used but it is not declared when
we declare it(name var) as String pw returns the password we have entered
Is there any correction in the above code.
