If the while loop condition never evaluates to False, then we will have an infinite loop, which is a loop that never stops automatically, in this case we need to interrupt externally. There is no difference in bytecode between while (true) and for (;;) but I prefer while (true) since it is less confusing (especially for someone new to Java). When one loop appears inside another it is called an indented loop. A bounded loop is a loop with a known iteration count, like : for(int i=0;i<10;i++){ } As you see, you're guaranteed (unless something like some Exception or a break statement occurs), that there will be 10 iterations. print(e + " ");, A loop is a structure that allows repeated execution of a block of statements. do c.
