• Arrays and lists are indexed starting from 0.

• Arrays and lists are commonly used in programming for storing and manipulating data.

• Example of an array: ['apple', 'banana', 'orange']

• Example of a list: [1, 'hello', True]

My three strengths are attention to detail, problem-solving skills, and ability to work well under pressure.

• Attention to detail: I have a keen eye for spotting errors and ensuring accuracy in my work.

• Problem-solving skills: I am able to analyze complex situations and come up with effective solutions.

• Ability to work well under pressure: I can remain calm and focused in high-pressure situations, allowing me to perform at my best.

Primitive data types are basic data types provided by Java, such as int, double, boolean, char, etc.

• Primitive data types are predefined by the language and not objects

• They are used to store simple values directly in memory

• They have a fixed size and do not have any methods

• Examples include int for integers, double for floating-point numbers, boolean for true/false values, char for characters

JIT stands for Just-In-Time compiler. It is a part of the Java Virtual Machine (JVM) that compiles bytecode into machine code at runtime.

• JIT is responsible for improving the performance of Java applications by compiling frequently executed code into native machine code.

• It analyzes the code at runtime and identifies the hotspots, i.e., the code that is executed frequently.

• JIT compiles the hotspots into machine code and stores them in the code cache for future use.

• This process ...read more
