Accenture Application Developer Interview Questions, Process, and Tips for Experienced

Functional interfaces in Java are interfaces with only one abstract method, allowing lambda expressions to be used for implementation.

• Functional interfaces can have multiple default methods but only one abstract method.

• They can be implemented using lambda expressions.

• Examples include java.lang.Runnable, java.util.Comparator, and java.util.function.Predicate.

Polymorphism in CPP allows objects of different classes to be treated as objects of a common superclass.

• Polymorphism allows for functions to be called on objects of different classes through a common interface.

• There are two types of polymorphism in CPP: compile-time (function overloading, operator overloading) and runtime (virtual functions).

• Example: A base class 'Shape' with virtual function 'draw()' can have subclass...read more

For loop is used when the number of iterations is known, while loop is used when the condition is true.

• For loop is used when the number of iterations is known beforehand.

• While loop is used when the condition needs to be checked before each iteration.

• For loop is more concise and easier to read for simple iterations.

• While loop is more flexible and can handle complex conditions.

• Example: for(int i=0; i<5; i++) { //code }

• Ex

A do while loop is a control flow statement that executes a block of code at least once, and then repeatedly executes the block as long as a specified condition is true.

• Initialize a variable outside the loop

• Use the do keyword to start the loop

• Write the code block to be executed inside the loop

• Use the while keyword followed by the condition to continue the loop

Exception handling is a mechanism to handle errors or exceptional situations in a program.

• It allows the program to gracefully handle unexpected situations without crashing.

• Exceptions can be caught and handled using try-catch blocks.

• Common exceptions include NullPointerException, ArrayIndexOutOfBoundsException, and IOException.

• Exception handling helps in improving the robustness and reliability of the software.

Use bitwise XOR operation to swap two integers without a temp variable.

• Use XOR operation to swap two integers: a ^= b, b ^= a, a ^= b

• Example: int a = 5, b = 10; a ^= b; b ^= a; a ^= b; // Now a = 10, b = 5

P2P cycle refers to procure-to-pay cycle, which involves the process of obtaining goods or services from a supplier and paying for them.

• The cycle starts with the need for goods or services, followed by identifying suppliers and negotiating terms.

• Purchase orders are created, goods are received, and invoices are processed for payment.

• The final step involves reconciling payments and closing out the transaction.

• Example: A ...read more

Data from an Excel sheet can be brought into Databricks using the read method in Databricks.

• Use the read method in Databricks to read the Excel file.

• Specify the file path and format (e.g. 'xlsx') when using the read method.

• Transform the data as needed using Databricks functions and libraries.

• Example: df = spark.read.format('com.crealytics.spark.excel').option('useHeader', 'true').load('file.xlsx')
