Reflection API is a feature in Java that allows inspection of classes, interfaces, fields, and methods at runtime.

• Reflection API provides a way to examine or modify the behavior of methods, classes, and interfaces at runtime.

• It allows you to access private fields and methods of a class.

• It is used in frameworks like Spring and Hibernate to create objects dynamically.

• Examples of using reflection API include creating...read more

We use various modelling methods in NX depending on the type of design and requirements.

• NX supports various modelling methods such as parametric, direct, synchronous, and freeform.

• Parametric modelling is used for designs that require precise control over dimensions and relationships between features.

• Direct modelling is used for quick modifications to existing designs without affecting the original design intent.

• Sy...read more

Interfaces in components can be verified through various methods.

• Verify the input and output parameters of the interface

• Check if the interface adheres to the defined standards

• Perform integration testing to ensure the interface works with other components

• Use tools like API testing frameworks to automate interface testing

• Perform boundary value analysis to ensure the interface handles extreme values correctly

Debugging is the process of identifying and fixing errors in software. Tools like debuggers and profilers aid in this process.

• Use debuggers like GDB or Visual Studio Debugger to step through code and inspect variables.

• Employ logging tools such as Log4j or Winston to capture runtime information.

• Utilize profilers like JProfiler or YourKit to analyze performance bottlenecks.

• Static analysis tools like SonarQube can he...read more
