Trouble returning the correct boolean value

I am trying to create a program to check a password. All 5 conditions must be true for the password to be valid. The problem I am having is if the entered password is long enough, the password is automatically valid even if the other conditions are not valid. I have tried changing many small things, but haven't been able to get it to check all the conditions. Any help is much appreciated!

public class Password
{
//Program main method
public static void main(String [] args)
{
String another = "y";
while (another.equalsIgnoreCase("y"))
{
Scanner scan = new Scanner(System.in);
System.out.print("Enter a password: ");
String password = scan.nextLine();
//Print output
if (checkPassword(password))
{
System.out.println("Entered Password: " + password);
System.out.println("Judgement: " + "Valid password");
System.out.println("Re-run Program (y/n)? ");
another = scan.next();
}
else 
{
System.out.println("Entered Password: " + password);
System.out.println("Judgement: " + "Invalid password");
System.out.println("Re-run Program (y/n)? ");
another = scan.next();
}
}
}
//
public static boolean checkPassword(String password)
{
if(!minChars(password)) 
{
return false;
}
else if (!onlyCharsAndDigits(password)) 
{
return false;
}
else if (!minDigits(password)) 
{
return false;
}
else if (!minLowerCase(password)) 
{
return false;
}
else if (!minUpperCase(password)) 
{
return false;
}
return true;
}
//
public static boolean minChars(String password)
{
if (password.length() > 8) {
return true;
}
else {
return false;
}
}
//method to test password has letters and digits or not
public static boolean onlyCharsAndDigits(String password)
{
for(int i=0;i < password.length();i++)
{
if(!Character.isLetter(password.charAt(i)) && !Character.isDigit(password.charAt(i)))
{
return false;
}
}
return true;
}
//method to test password has letters and digits or not
public static boolean minDigits(String password)
{
int numberOfDigits = 0;
for(int i=0;i < password.length();i++)
{
if(Character.isDigit(password.charAt(i)));
{
numberOfDigits++;
}
}
return numberOfDigits >= 3;
}
//method to test password has letters and digits or not
public static boolean minLowerCase(String password)
{
int numberOfLowerCase = 0;
for(int i=0;i < password.length();i++)
{
if(Character.isLowerCase(password.charAt(i)));
{
numberOfLowerCase++;
}
}
return numberOfLowerCase >= 3;
}
//method to test password has letters and digits or not
public static boolean minUpperCase(String password)
{
int numberOfUpperCase = 0;
for(int i=0;i < password.length();i++)
{
if(!Character.isUpperCase(password.charAt(i)));
{
numberOfUpperCase++;
}
}
return numberOfUpperCase >= 3;
}
}

Change all else if to if in the checkPassword method.

An else if branch will not be executed if any of the preceding branches are executed.

Your code can be simplified as

public static boolean checkPassword(String password) {
return minChars(password) && onlyCharsAndDigits(password) 
&& minDigits(password) && minLowerCase(password) && minUpperCase(password);
}
