How do you convert a character array to a String?
I have this code

Console c = System.console();
if (c == null) {
    System.err.println("No console.");
    System.exit(1);
}
char [] password = c.readPassword("Enter your password: ");

I need to convert that to a String so I can verify 

if(stringPassword == "Password"){
    System.out.println("Valid");
}

Can anyone help me with this?

There is a reason char[] is used for passwords over Strings. – Jeffrey 18 hours ago

Use the String(char[]) constructor.

char [] password = c.readPassword("Enter your password: ");
String stringPassword = new String(password);

And when you compare, don't use ==, use `.equals():

if(stringPassword.equals("Password")){

You should also add in the bit about not using == to compare string's equality. – jmort253 19 hours ago

and as a best practice, if your comparing a variable with a string literal or a constant, always call the .equals method from the string literal or a constant to avoid possible null pointer exception, i.e. "Password".equals(stringPassword) – jay c. 18 hours ago

You'll want to make a new String out of the char[]. Then you'll want to compare them using the .equals() method, not ==.

So instead of 

if(stringPassword == "Password"){

You get

if("password".equals(new String(stringPassword))) {
