Getting field type in a method in eclipse

Question

How do I programmatically get the field type from a statement inside a method like this :

Foo foo = getSomeFoo();

If it is field, I can know the type of the element.

You need to use Eclipse's AST

ICompilationUnit icu = ...

ASTParser parser = ASTParser.newParser(AST.JLS3);
parser.setResolveBindings(true);
parser.setSource(icu);
CompilationUnit cu = (CompilationUnit) parser.createAST(null);
cu.accept(new ASTVisitor() {
    @Override
    public boolean visit(VariableDeclarationStatement node) {
        System.out.println("node=" + node);
        System.out.println("node.getType()=" + node.getType());
        return true;
    }
});
