And finally, you have the option to implement something simpler yourself, in case you need just iteration and almost nothing else.I’ve done it here – DiskBackedArrayList.java. It doesn’t support many things (not all methods are overridden to throw an exception, but they should). But mos...

For example:-Int boller[15];When we type the above statement the compiler will reserved a 15 consecutive memory locations for the integer array boller.How to store values in One-Dimensional integer Array:-There are three methods to store values in them....
3. Then it will again repeat the above steps for all the elements by excluding the greatest one. 4. It will continue to repeat until the array becomes sorted. Let’s take a look towards the following example which will illustrate and completely describe the use, working and operations of ...
If the candidate misses one of the requirements for immutability, invent a scenario in which immutability is violated and see how they handle it.You could ask about the internal data structure that was chosen (here ArrayList). Alternatives are Vector (needless synchronization) and raw arrays (...
Please remember, this is not going to be a “be-all and end-all” entrepreneurship guide, but it will be enough to give you a “nudge” towards the correct direction. Some of the material we are going to provide will need quite a time to properly digest. For this reason, make sure ...
