Test Your Java Skills
Test your Java across core syntax and types, methods/overloading/scope, collections/generics/control flow, and exceptions/concurrency/idioms. 30 code-reading questions, instant score by category, free with no signup.
Java Test అంటే ఏమిటి?
This is a scenario-based Java test: 30 short code snippets, each followed by a question about what actually happens when it runs. A String comparison with == that quietly checks references instead of content. An Integer autoboxing cache that makes == appear to work below 128 and silently fail above it. A finally block that overrides a return value without anyone noticing. You pick the answer that matches what the code actually prints or does, not what looks like it should happen.

The 30 questions cover four areas — core syntax and types, methods/overloading/scope, collections/generics/control flow, and exceptions/concurrency/idioms. Those four are the places where reading code and running code quietly diverge, and where a job posting's Strong Java usually turns out to mean something specific once you are in the interview. You get a score in each area, so a weak spot shows up as a weak spot rather than as a lower total.
It takes about six minutes, there is no signup, and there is no code to write or compile — every question is read-and-predict, the same way a senior engineer reviews a pull request. Knowing the syntax and knowing what a specific snippet does at runtime are different skills, and this measures the second one.
