TCS, Infosys, Wipro, Accenture and almost every mid-size IT services firm has Java in its tech stack. If you are a BCA or BTech student targeting placements in 2026, Java is a must-have skill.

Why Java is the #1 placement language in India

• Enterprise dominance: most banking, insurance and government-IT backends in India run on Java Spring/Hibernate stacks.
• Android development: Java is still used widely in Android apps alongside Kotlin.
• Interview familiarity: FAANG-style interviews, service company tests and campus drives all accept Java solutions. The verbose syntax is a feature — it forces you to think clearly about types and structure.
