+# "Nicht Haskel 2.0" Java Compiler
+
+Realisation of a subset of the Java Standard Compiler in the course Compiler Construction of the 4th semester Computer Science at the Duale Hochschule Stuttgart (Horb).
+
+This project aims to provide a simplified version of the Java compiler, focusing on key language features and demonstrating the principles of compiler construction.
+
+## Realised Java syntax
+
+- **Data types**: `int`, `boolean`, `char`
+- **Access modifier**: `public`, `protected`, `private`
+- **Operators**: `=` `+` `-` `*` `%` `/` `>` `<` `>=` `<=` `==` `!=` `!` `&&` `||` `++` `--`
+- **Keywords**: `class`, `this`, `while`, `do`, `if`, `else`, `for`, `return`, `new`, `switch`, `case`, `break`, `default`, `:`
+- **Statements**:
+    - `if` ... `if else` ... `else`;
+    - `while` ... ;
+    - `do` ... `while`;
+    - `for`;
+- **Comments**:
+    - Single line: `// comment`
+    - Multi-line: `/* comment */`
+- **Further functions**:
+    - All methods are overloadable
+    - High maintainability and expandability through implementation of the visitor pattern
+    - Logging Input and Outputs
+    - Error Handling in the Semantic Check

+
+## Distribution of the realisation
+
+### i22030 & i22035
+Ausführliche Beschreibung der Parser Umsetzung:
+
+![Parserumsetzung](Parser_Dokumentation.pdf)
+
+Parser:
+- Grammar -> (src/main/java/parser/grammar)
+- Scanner 
+- Parser
+- Abstract Syntax Tree (AST) -> (src/main/java/ast)
+- AstBuilder -> (src/main/java/parser/astBuilder)
+
+Parser tests:
+- ParserTests -> (src/test/java/parser)
+- TestCases -> (src/test/resources/input/singeFeatureTests)
+
+Other:
+- Documentation -> (README.md)
+- Ast Class-Diagramm -> (ast.png) 
+- PowerPoint
+
+### i22005
+Semantic check:
+- Set all types and check whether types have been used correctly
+- Contexts -> (src/main/java/semantic/context)
+- Exceptions Handling -> (src/main/java/semantic/exceptions)
+
+Semantic Tests:
+- Typing and Type checking -> (src/test/java/semantic/EndToTypedAstTest)
+- Exception and feature test -> (src/test/resources/input/typedAstExceptionsTests)
+
+### i22007
+Bytecode generation:
+- Complete bytecode generation -> (src/mein/java/bytecode)
+
+### i22011
+Tests and execution:
+- Makefile
+- Running Compiler -> (src/main/main)
+- Running E2E tests -> (src/test/main)
+- Typing and Type checking -> (src/test/java/semantic/EndToTypedAstTest)
+
+
+## Used Tools
+
+- [Maven 4.0](https://maven.apache.org/index.html)
+  - Used for automating the build process and managing dependencies.
+- [ANTLR4 v.13.1](https://www.antlr.org/)
+  - Used to parse the input Java code into the Abstract Syntax Tree.
+
+## How to run the compiler
+### Possibilities
+### 1. Start miniCompiler using make:
+Make needs to be installed
+```bash
+cd .\src\test\ ; make clean compile-miniCompiler
+```
+
+### 2. Start miniCompiler using jar:
+If you do not have the .jar, download it [here](https://gitea.hb.dhbw-stuttgart.de/i22005/NichtHaskell2.0/src/branch/main/JavaCompiler-1.0-jar-with-dependencies.jar) or compile it using mvn package or make first
+```
+java.exe -DgenJar=bool -DgenClass=bool -jar path_to_jar\jarName.jar 'path_to_input_file.java' 'path_to_output_directory'
+```
+
+Example (jar needs to be in the target directory)
+```bash
+ java.exe -DgenJar=true -DgenClass=true -jar .\target\JavaCompiler-1.0-jar-with-dependencies.jar 'src/main/resources/input/CompilerInput.java' 'src/main/resources/output'
+```
+
+- set DgenJar true, to generate the jar, false for no jar
+
+```
+ DgenJar=true
+```
+
+- set DgenClass true, to generate class files, false for no class files
+
+```
+ DgenClass=true
+ ```
