In this section, you will create your first programming loop in Java using thewhilekeyword. You’ll use a singleintvariable to control the loop. Theintvariable will be calledxand will have an initial value of3. While, or as long as,xis bigger than0, the loop will continue executing a ...
Loop through the items of a HashMap with a for-each loop.Note: Use the keySet() method if you only want the keys, and use the values() method if you only want the values:ExampleGet your own Java Server // Print keys for (String i : capitalCities.keySet()) { System.out.println(...

Note: the memory leak isnotdue to the infinite loop on line 14: the infinite loop can lead to a resource exhaustion, but not a memory leak. If we had properly implementedequals()andhashcode()methods, the code would run fine even with the infinite loop as we would only have one element...
Once the loop code is completed,iis incremented by one and the loop begins again. At the end of the third loop,iis increased to four. When the next loop begins, our condition is met, so the loop stops. Related:Core Java Concepts You Should Learn When Getting Started ...
