To format our inner entries, let’s implement a helper function with a recursion and a left padding parametrized: voidprintMap(intleftPadding, Map<?, ?> map){for(Map.Entry<?, ?> entry : map.entrySet()) {if(entry.getValue()instanceofMap) { System.out.printf("%-15s :%n", entry....
capitals.forEach((k, v) -> System.out.format("%s: %s%n", k, v)); With forEach we iterate over all pairs of the map. Iteration with enhanced for loopThe enhanced for loop can be used to iterate over a HashMap. Main.java
The Signature class provides access to the functionality of a digital signature algorithm. A DSA KeyFactory class supplies a DSA private or public key (from its encoding or transparent specification) in a format usable by the initSign or initVerify methods, respectively, of a DSA Signature object...
