Output? • //classes will compile fine bcos both r throwing run time exceptions • class TestOverride { • void solution() throws NullPointerException { • System.out.println("super"); • } • } • • class TestSubOverride extends TestOverride { • void solution() throws RuntimeException { • System.out.println("sub"); • } • } 2. Given array {4,5,6,1,2,4}; how do u search particular element ex:1? Ans: he was looking for best search algorithm – ans is binary search algorithm 3. Consider I have huge data which is stored randomly, which data structure is best for retrieval with performance of O(1)? Ans: Hashmap bcos of performance O(1) always 4.
