You are asked that if you have a linked list in which you can traverse only in one direction, and if that linked list has a loop in it, how you will detect it?? Answer 1. Integer.MAX_VALUE is the maximum value that an int can store in Java. Stephan van Hulst wrote:The only way to kill a task (not a thread, you can't guarantee a thread will be killed if you use a thread pool, unless you use the incredibly dangerous Thread.stop()) is to communicate with it using signals. I have a simple program for server/client communication using sockets. For type int, the default value is zero. When you know exactly how many times you want to loop through a block of code, use the for loop instead of a while loop: Syntax for (statement 1; statement 2; statement 3) { // code block to be executed} Statement 1 is executed (one time) before the execution of the code block. So, you wanna know how to escape an infinite loop, eh? To terminate this, we are using break.If the user enters 0, then the conditon of if will be satisfied and break will be executed and the loop will be terminated.. continue.
