Arrays in Java are fixed in size and cannot be resized once initialized.
Example: ArrayList<String> arrayList = new ArrayList<String>(); String[] array = new String[5];
- Q2. About spring boot
- Q3. Write code for dynamic arrays
- Ans.
Code snippet to implement dynamic arrays with add, remove, and access methods.
Use a list or vector data structure to implement dynamic arrays.
For adding elements, use the append or push_back method.
For removing elements, use the erase or remove method.
For accessing elements, use the index operator or at method.
- Q4. For loop, for each
- Q5. What do u know about java
- Ans.
Java is a popular programming language known for its platform independence and object-oriented approach.
Java is an object-oriented programming language

- Q8. Linked list - node insertion, deletion in java
- Ans.
Linked lists allow dynamic data structure manipulation with efficient node insertion and deletion operations.
A linked list consists of nodes, where each node contains data and a reference to the next node.
Insertion can be done at the head, tail, or any specific position in the list.
Example of insertion at the head: Create a new node and set its next to the current head, then update the head.
Deletion involves removing a...
- Q9. Heaps in java, how does internal memory allocation happen for heaps
- Ans.
In Java, heaps are used for dynamic memory allocation. Internal memory allocation in heaps is managed by the JVM.
Heaps in Java are used for storing objects and dynamically allocated memory.
Memory allocation in heaps is managed by the Java Virtual Machine (JVM).
The JVM uses a technique called garbage collection to reclaim memory from objects that are no longer in use.
Objects in the heap are allocated memory based on the...
