when editing a String in XML I need to add line breaks. And I wanted to ask what is the RIGHT form when programming for android? Because <br> works but ECLIPSE marks the area as problematic. If I check out suggestions Eclipse tells me that I shall add a end tag </br> - IF I add that the line break dissapears... So the one works but is marked as problematic, the other works not but Eclipse tells me its ok.. What form shall I use? Christopher Orr Use \n for a line break and \t if you want to insert a tab. You can also use some XML tags for basic formatting: <b> for bold text, <i> for italics,

This question already has an answer here: How do I break out of nested loops in Java? 35 answers I have been using Java for quite some time, yet my education in loops is somewhat lacking. I know how to create every loop that exists in java and break out of the loops as well. However, I've recently thought about this: Say I have two nested loops. Could I break out of both loops using just one break statement? Here is what I have so far. int points = 0; int goal = 100; while (goal <= 100) { for (int i = 0; i < goal; i++) { if (points > 50) { break; // For loop ends, but the while loop does not }

I am trying to convert the if else clause to a ternary within a while loop, however it's not allowing me to have a break after the question mark, pointing an error at the break as an invalid expression. How would I go about turning this simple if else into a ternary like so. while (true) { Console.WriteLine("Enter 3 words seperated by spaces: "); var input = Console.ReadLine(); //input == "" ? break : ConvertToPascal(input); if (input == "") break; else ConvertToPascal(input); } } It isn't possible using the ternary operator, but you can simplify your code structure as follows: string input;

I have this method that checks the username and password of a user before login. Now my for loop checks only the first item, it finds that the first condition, u.getRole().equalsIgnoreCase("recruiter") is not satisfied for the first item, so instead of going and checking the second item it just breaks and returns null. Why does this happen? Here is my method: public User check(String userName, String password) throws AdException { try { begin(); Query q = getSession().createQuery("from User"); ArrayList<User> list = (ArrayList<User>) q.list(); System.out.println("recruiterList is: " + list);

So I have this MySQL database and a table and in the rows there a lot of "," in them, and I wish when they are output on the screen with PHP to be switched to " " instead of coma, how do I do that? I mean, this is a example, it stands like this: hello,no,thanks and instead of being output like that I would like it to be output as: hello no thanks How do I do that? Could someone do it for me? Would be very friendly. Assuming there are no CSV quoting issues: $newStr = str_replace( ',', '<br>', $string ); EDIT: After seeing your rollback, i see that you actually want to replace the , with a

I have some code: def playAgain1(): print("Would you like to keep boxing or quit while you are ahead? (y/n)") playAgain = input().lower() if(playAgain.startswith('y') == False): print("Whatever you chicken.") break I want it to break the loop if playAgain() doesn't start with y . Whenever I try, I get the error: 'break' outside loop How could I write this better to make it work? As Matt Bryant's answer states, you can't break outside a loop but can just return from the function. I would add that you probably need to return a value from your function, so that the main programme loop knows
