If your password must have at least one capital letter and at least one number your logic is wrong. You should have two booleans.

boolean hasCapitalLetter = false;
boolean hasNumber = false;

for (int i = 0;i<Password.getText().length(); i++) {
    char i1 = Password.getText().charAt(i);

    if (!hasCapitalLetter) {
        hasCapitalLetter = Character.isUpperCase(i1);
    }
    if (!hasNumber) {
        hasNumber = Character.isDigit(i1);
    }
    if (hasCapitalLetter && hasNumber) {
        return true;
    }
}

return false;
