static field initialization using AST [message #780696]

I need to create a static String variable with a default value (e.g. public static final String COUNTRY="INDIA";) using Eclipse AST. I'm able to create such a varibale using SingleVariableDecleration or FieldDecleration. But I'm not sure how to initialize the same using AST.

This is what I could implement==> public static final String COUNTRY;

This is what I could not implement==> public static final String COUNTRY="INDIA";

Please help me to know how can I do this. Thanks in advance,

Shyam

For the iterested candidates, I'm pasting the LOC here.

VariableDeclarationFragment vdf = ast.newVariableDeclarationFragment();

StringLiteral literal = ast.newStringLiteral();
literal.setLiteralValue("INDIA");

vdf.setInitializer(literal );
vdf.setName(ast.newSimpleName("COUNTRY"));

FieldDeclaration fieldDeclaration= ast.newFieldDeclaration(vdf);
fieldDeclaration.setType(ast.newSimpleType(ast.newSimpleName("String")));

fieldDeclaration.modifiers().add(ast.newModifier(ModifierKeyword.PUBLIC_KEYWORD));
fieldDeclaration.modifiers().add(ast.newModifier(ModifierKeyword.STATIC_KEYWORD));
fieldDeclaration.modifiers().add(ast.newModifier(ModifierKeyword.FINAL_KEYWORD));

type.bodyDeclarations().add(fieldDeclaration);
