Description:

This pull request introduces support for parsing and handling yield statements in Java source code within the sourcecode-parser package. The changes include modifications to the core parsing logic, the addition of new test cases, and updates to the model and query handling to accommodate yield statements.

Parsing and Model Updates:

• Added YieldStmt to the Node struct in sourcecode-parser/graph/construct.go and implemented parsing logic for yield statements. [1] [2]
• Introduced ParseYieldStatement function in sourcecode-parser/graph/java/parse_statement.go to handle the parsing of yield statements.
• Added YieldStmt struct and its methods in sourcecode-parser/model/stmt.go to represent yield statements in the model.

Testing Enhancements:

• Updated TestBuildGraphFromAST in sourcecode-parser/graph/construct_test.go to include test cases for yield statements and adjusted expected node and edge counts. [1] [2]
• Added TestParseYieldStatement in sourcecode-parser/graph/java/parse_statement_test.go to verify the correct parsing of various yield statement scenarios.
• Created TestYieldStmt in sourcecode-parser/model/stmt_test.go to test the ToString method of the YieldStmt struct.

Query Handling:

• Added GetYieldStmt method in sourcecode-parser/graph/query.go and updated generateProxyEnv to handle yield statements in queries. [1] [2] [3] [4]

Example Usage:

• Included a switch statement with yield in test-src/android/app/src/main/java/com/ivb/udacity/movieDetailActivity.java to demonstrate the new functionality.

Checklist:

• Tests passing (gradle testGo)?
• Lint passing (golangci-lint run this requires golangci-lint)?
