equals

I have a WPF application with two PasswordBoxes, one for the password and another for the password to be entered a second time for confirmation purposes. I was wanting to use PasswordBox.SecurePassword to get the SecureString of the password, but I need to be able to compare the contents of the two PasswordBoxes to ensure equality before I accept the password. However, two identical SecureStrings are not considered equal: var secString1 = new SecureString(); var secString2 = new SecureString(); foreach (char c in "testing") { secString1.AppendChar(c); secString2.AppendChar(c); } Assert

I have two lists of arrays. How do I easily compare equality of these with Java 8 and its features , without using external libraries? I am looking for a "better" (higher-level, shorter, more efficient) solution than brute-force code like this (untested code, may contain typos etc, not the point of the question): boolean compare(List<String[]> list1, List<String[]> list2) { // tests for nulls etc omitted if(list1.size() != list2.size()) { return false; } for(i=0; i<list1.size(); ++i) { if(!Arrays.equals(list1.get(i), list2.get(i))) { return false; } } return true; } Or, if there isn't any

This question already has an answer here: Comparing numbers in Bash 8 answers I have a bash variable depth and I would like to test if it equals 0. In case yes, I want to stop executing of script. So far I have: zero=0; if [ $depth -eq $zero ]; then echo "false"; exit; fi Unfortunately, this leads to: [: -eq: unary operator expected (might be a bit inaccurate due to translation) Please, how can I modify my script to get it working? Looks like your depth variable is unset. This means that the expression [ $depth -eq $zero ] becomes [ -eq 0 ] after bash substitutes the values of the variables

I need to implement the equals method in some class A. Class A has an orderer collection of Enum type, and the behaviour I want to achive is that equals returns true for two instances of Class A that have exactly the same Enum values in the collection (in exactly the same positions of the collection). As I'm new to java, I'm having problems with this, and I dont know how to properly implement equals or the hashcode methods, so any help would be good :) If you're using eclipse (netbeans has similar features, as do most java IDEs), you can simply got to the "Source" menu, and choose "Generate

i've got a problem: I need to find if list equal to the second one, for example: (set%eq? '(1 2 3) '(1 2 3)) ===> #t (set%eq? '(1 2 3) '(2 3 4)) ===> #f That examples are correct in my program, but this one is not: (set%eq? (quote ((quote one) (quote two) (quote three))) (quote ((quote one) (quote two) (quote three)))) ====> #f but i need #t what's wrong? this is my program: (define (set-eq? xs ys) (cond ((and (null? xs) (null? ys)) #t) ((null? ys) #f) ((eq? (car xs) (car ys)) (set-eq? (cdr xs) (cdr ys))) ((eq? (car xs) (car (reverse ys))) (set-eq? (cdr xs) (cdr (reverse ys)))) (else #f)))
