Runnable companion for the ankurm.com article Top 50 Java Interview Questions for Freshers (2026) with Simple Answers.

One small demo per question, grouped in six classes. Tests assert what each demo prints and write the transcripts the article quotes. There is no docs/ folder on purpose: the explanations live in the article.

Component	Version	Verified against
JDK	25.0.5+8 (Temurin, LTS)	`java -version`
JUnit	6.1.3	`maven-metadata.xml` on Maven Central
Maven	3.9.11	`mvn -version`

export JAVA_HOME=/path/to/jdk-25 && export PATH="$JAVA_HOME/bin:$PATH"
cd fresher-qa
mvn test                  # 6 tests; rewrites output/01-06
./scripts/run-all.sh      # also regenerates output/07 (javac's own error messages for src/broken/)

Class	Questions	Transcript
`BasicsQa`	1-9	`output/01-basics.txt`
`OopQa`	10-20	`output/02-oop.txt`
`StringsQa`	21-27	`output/03-strings.txt`
`CollectionsQa`	28-38	`output/04-collections.txt`
`ExceptionsQa`	39-43	`output/05-exceptions.txt`
`ModernJavaQa`	44-50	`output/06-modern-java.txt`

src/broken/ holds five files that must NOT compile (one of them only fails below Java 25); scripts/compile-errors.sh runs javac on each and commits the real message to output/07-compile-errors.txt. They are excluded from the Maven build.
