以下示例显示java.io.Console.readPassword()方法的用法。
package com.jc2182;
import java.io.Console;
public class ConsoleDemo {
public static void main(String[] args) {
Console cnsl = null;
String alpha = null;
try {
// creates a console object
cnsl = System.console();
// if console is not null
if (cnsl != null) {
// read line from the user input
alpha = cnsl.readLine("Name: ");
// prints
System.out.println("Name is: " + alpha);
// read password into the char array
char[] pwd = cnsl.readPassword("Password: ");
// prints
System.out.println("Password is: "+pwd);
}
} catch(Exception ex) {
// if any error occurs
ex.printStackTrace();
}
}
}
让我们编译并运行以上程序,这将产生以下结果-
