Java program explaining the generation of Password

// Java code to explain how to generate random
// password
// Here we are using random() method of util
// class in Java
import java.util.*;
public class NewClass
{
public static void main(String[] args)
{
// Length of your password as I have choose
// here to be 8
int length = 10;
System.out.println(geek_Password(length));
}

// This our Password generating method
// We have use static here, so that we not to
// make any object for it
static char[] geek_Password(int len)
{
System.out.println("Generating password using random() : ");
System.out.print("Your new password is : ");

// A strong password has Cap_chars, Lower_chars,
// numeric value and symbols. So we are using all of
// them to generate our password
String Capital_chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
String Small_chars = "abcdefghijklmnopqrstuvwxyz";
String numbers = "0123456789";
String symbols = "!@#$%^&*_=+-/.?<>)";
String values = Capital_chars + Small_chars +
numbers + symbols;

// Using random method
Random rndm_method = new Random();

char[] password = new char[len];

for (int i = 0; i < len; i++)
{
// Use of charAt() method : to get character value
// Use of nextInt() as it is scanning the value as int
password[i] =
values.charAt(rndm_method.nextInt(values.length()));

}
return password;
}
}

Note : The password we are generating will change every time. As we have used random() method to generate the password.
