Amdocs Software Developer Interview Questions, Process, and Tips

Multithreading and data structures are important concepts in Java programming.

• Multithreading allows for concurrent execution of multiple threads within a single program.

• Data structures are used to organize and manipulate data efficiently.

• Examples of data structures include arrays, linked lists, stacks, and queues.

• Java provides built-in support for multithreading through the Thread class and the Runnable interface.

• Synch...read more

Swapping of numbers can be done using call by value, address and reference.

• Call by value: Pass the values of variables as arguments to the function. Swap the values inside the function.

• Call by address: Pass the addresses of variables as arguments to the function. Swap the values using pointers inside the function.

• Call by reference: Pass the references of variables as arguments to the function. Swap the values using ref

Reverse a given string
