Help me with my nested if statements in java (self-learning Novice)

I am having trouble with the following code that is supposed to ask questions about gender and age, and if over 20, ask if the user is married. If they a woman, 20+, and married then I title them "Mrs.", if woman, not married, but 20+, "Ms.", if man of 20+ years, and married or not, "Mr.", and if any user is under 20: just their name is put back without any title.

I feel like I've tried many ways to get this to work. I am trying to use nested ifs and AND in this code. The operations should make sense with the way I've structured them yet, if someone is 20+ and married, they always come out as a Mr.

Any help would be appreciated. TIA

The code.

import java.util.Scanner;

public class GenderGame
{
public static void main( String[] args )
{

Scanner keyboard = new Scanner(System.in);

String gender, first_name, last_name, married;
int age;

System.out.println( "What is your gender? (M or F):" );
gender = keyboard.next();
System.out.println( "First name: " );
first_name = keyboard.next();
System.out.println( "Last name: " );
last_name = keyboard.next();
System.out.println( "Age: ");
age = keyboard.nextInt();

String male, female, yes, no;

male = "M";
female = "F";
yes = "Y";
no = "N";



if( age >= 20 ) {
System.out.println( "Are you married, " + first_name + "? (Y or N) " );
married = keyboard.next();
if( gender == female && married == yes ) {
System.out.println( "Then you are called Mrs. " + first_name + " " + last_name + "." );
}
else if( gender == female && married == no ) {
System.out.println( "Then you are called Ms. " + first_name + " " + last_name + "." );
}
else {
System.out.println( "Then you are called Mr. " + first_name + " " + last_name + "." );
}
}

else {
System.out.println( "Then you are called " + first_name + " " + last_name + "." );
}

}
}
