Cobol to Java Convertor - A Transformation Utility application

Cobol to Java Converter - A Transformation Utility

 Trying to make an application that can effeciently converts COBOL code to Java.

This project is on going on...


The function identifies the block of codes in COBOL and categories it, based on
CobolConstants.divisionIdentifier


public Map<String,List<String>> createCodeblocks() throws IOException {
codeBlocks = new HashMap<>();
String line = null;
List<String> elements = null;
String key = null;
while (null != (line = bufferedReader.readLine())) {
if (CobolConstants.divisionIdentifier.contains(line)) {
if (null != elements) {
codeBlocks.put(key, elements);
codeConstructor(key,elements);
}
key = line;
elements = new ArrayList<>();
} else {
elements.add(line);
}
}

return codeBlocks;
}


CodeConstructor is trying to constructor java code by finding the proper class based on the identifierdivisions in COBOL

private void codeConstructor(String key, List<String> elements) {
// TODO Auto-generated method stub
switch (key) {
case "IDENTIFICATION DIVISION.":
identificationDivision = new IdentificationDivision(key, elements);
identificationDivision.getConvertedCode();
break;

default:
break;
}
}



This step create the Java code from the COBOL code given

public void getConvertedCode() {

for(String code : codes) {
if(code.contains("PROGRAM-ID")) {
String name = code.replace("PROGRAM-ID.", "").replace(".", "");
System.out.println(" public class "+getNamingUtility().createClassName(name));

}
}

}

Input

PROGRAM-ID. Iteration-If

Output

public class iterationIf
