Robustness and Security
Java was designed with robustness in mind. Features like strong type checking, exception handling, and automatic garbage collection contribute to the language's reliability. Java's garbage collector automatically manages memory by reclaiming space occupied by objects that are no longer in use, reducing the risk of memory leaks and crashes.

Security is another core aspect of Java. The language includes a built-in security model that restricts access to system resources, preventing malicious code from causing harm. The JVM's bytecode verification process ensures that Java programs are safe to execute, further enhancing security.

Multithreading and Concurrency
Java has robust support for multithreading, allowing developers to create programs that can perform multiple tasks simultaneously. This is particularly important in modern computing environments, where efficient use of multi-core processors is crucial for performance. Java’s concurrency utilities, introduced in later versions, make it easier to write thread-safe code.

Programming and problem solving with Java involves leveraging the language's features to design, implement, and optimize solutions for various computational problems. Here’s a step-by-step guide on how to approach programming and problem solving with Java:

Step 1: Understand the Problem
Read the Problem Statement: Carefully read and understand the problem statement. Identify the inputs, outputs, constraints, and requirements.
Clarify Doubts: If anything is unclear, seek clarification. Ensure you have a comprehensive understanding of what needs to be solved.
Step 2: Plan the Solution
Break Down the Problem: Decompose the problem into smaller, manageable sub-problems or tasks.
Choose the Right Approach: Decide on the approach to solve the problem. This could involve choosing the right data structures, algorithms, or design patterns.
Pseudocode: Write pseudocode to outline the steps of your solution. This helps in visualizing the flow and logic before actual coding.
Step 3: Implement the Solution in Java
Set Up Your Environment: Ensure you have a suitable Integrated Development Environment (IDE) like IntelliJ IDEA, Eclipse, or NetBeans set up for Java development.
Write the Code: Translate your pseudocode into Java code. Focus on implementing one part at a time and ensure each part works correctly before moving on.
