Java Program to Add variable to current scope

How to write a C Program to Add variable to current scope in Java Programming ?

Solution:

1.  @Override
2.   public Void visitInitialisation(InitialisationContext ctx) {
3.     // TODO Add variable to current scope
4.     // TODO Check RHS type is equal to variable type
5.     // System.out.println("Visiting initialisation context");
6.     String type = ctx.type().getText();
7.     String ident = ctx.ident().getText();
8.     try {
9.       scopeHandler.add(ident, type);
10.     } catch (Exception e) {
11.       System.out.println(e.getMessage());
12.     }
13.     visit(ctx.assign_rhs());
14.     if (!nodeType.equals(type)){
15.       if(type.contains("[]") && type.substring(0, type.length() -2).equals(nodeType)){
16.         return super.visitInitialisation(ctx);
17.       }
18.       System.err.println("Error: Incompatible type at ' "
19.           + ctx.assign_rhs().getText() + " ' (Expected: " + type + ", Actual: "
20.           + nodeType + ")");
21.     }
22.  
23.     return super.visitInitialisation(ctx);
24.   }
