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...
