You can traverse through the Compilation unit of the Java class and visit the TypeDeclaration AST node. The below code can then be used to check if it is not a top-level class, i.e an inner class.
public boolean visit(TypeDeclaration typeDeclarationStatement) { if (!typeDeclarationStatement.isPackageMemberTypeDeclaration()) { System.out.println(typeDeclarationStatement.getName()); // Get more details from the type declaration. } return true; } For getting anonymous inner classes use the below code too:
public boolean visit(AnonymousClassDeclaration anonyomousClassDeclaration) { System.out.println(anonyomousClassDeclaration.toString()); return true; } Details on Class traversal using JDT can be found from below link:

i used the code below but it does not display all inner classes

Does the code doesn't display any inner classes, or is it problem with some specific inner class (anonymous/method inner class)?

ASTParser parser = ASTParser.newParser(AST.JLS3); parser.setKind(ASTParser.K_COMPILATION_UNIT); parser.setSource(fileName.toString().toCharArray()); parser.setResolveBindings(true); parser.setCompilerOptions(options); final CompilationUnit cu = (CompilationUnit) parser.createAST(null); cu.accept(new ASTVisitor() { public boolean visit(TypeDeclaration typeDeclarationStatement) { if (!typeDeclarationStatement.isPackageMemberTypeDeclaration()) { System.out.println(typeDeclarationStatement.getName()); } return true; }
If you have an IType instance (type) then you can query the inner classes by
type.getTypes(); which will give you an array of the immediate member types declared by this type.

But you have a ICompilationUnit instance? If so, you can get all top-level type declarations of this compilation unit with ICompilationUnit.getTypes()
