Lisa's notes: musings on daily life, work, study, personal growth, and casual reflections.
This tutorial walks through the fundamentals of Java one-dimensional arrays, covering declaration syntax, memory allocation with new, default values, direct initialization, element access, out‑of‑bounds handling, and element modification with concrete code examples and expected outputs.
The article explains Huawei's IPD (Integrated Product Development) workflow from a project perspective—covering concept, planning, development, and release stages—and provides a detailed glossary of IPD‑related terminology used throughout the product lifecycle.
This article explains step‑by‑step how to use both while‑loops and for‑loops in Python to generate a formatted 9×9 multiplication table, detailing the loop logic, code syntax, and the exact output produced for each row.
The article traces the origins of humanoid robots, explains safety principles like Asimov's Three Laws, outlines generational classifications, breaks down the upstream‑midstream‑downstream industry chain with component cost shares and key vendors, and discusses business models, challenges, and AI‑driven opportunities that make entry difficult for ordinary people.
This tutorial explains how break and continue control loop execution in Python, provides concrete while‑loop examples with their outputs, and demonstrates both for‑ and while‑based nested loops for printing multi‑row patterns, illustrating syntax and behavior step by step.
This note explains why Java introduces arrays, defines arrays as collections of same‑type variables, demonstrates the limitation of using individual variables for many items, and outlines six key characteristics of Java arrays, including fixed length, zero‑based indexing, and default values.
The article explains Python's for‑in loop syntax, describes common iterable types such as strings, lists, tuples and sets, details how the range function defines start and end values, and provides concrete code examples that print numbers, list elements and characters from both English and Chinese strings.
This article provides a comprehensive walkthrough of Java's operators and expressions, covering arithmetic, assignment, increment/decrement, relational, logical, bitwise, and ternary operators, their syntax, evaluation rules, precedence, and practical code examples to help beginners master Java fundamentals.
This article explains Java's primitive data types—including integer, floating‑point, character, and boolean types—covers their memory sizes, value ranges, literal syntax, automatic and explicit type conversions, and provides concrete code examples and tables for reference.
This note introduces Java constants and variables, covering their definitions, naming conventions, declaration syntax, initialization rules, multiple declarations, and how constants differ from mutable variables through concrete code examples.
