A Junior Java Developer should have a solid understanding of Java programming, object-oriented principles, and basic software development concepts, often supported by a relevant degree or coding bootcamp. Familiarity with tools such as IntelliJ IDEA or Eclipse, version control systems like Git, and frameworks like Spring Boot is typically expected. Strong problem-solving abilities, attention to detail, and effective teamwork are important soft skills in this role.
