While designing loops, we can always commit mistakes like forgetting to update the condition variable or not defining a proper condition which leads to the loop being run infinite number of times. The only difference is that break statement terminates the loop whereas continue statement passes control to the conditional test i.e. This laziness is achieved by a separation between two types of the operations that could be executed on streams: intermediate and terminaloperations. Now, if we want to make our for loop go infinitely, we can try the following ways: This program will print “Hello World” infinitely since the condition “i>0” will always be true.
