ContentValues cv = new ContentValues(); can be directly inside a class declaration. Non-declarations, such as: cv.put(colDeptID, 1); cv.put(colDeptName, "Sales"); db.insert(deptTable, colDeptID, cv); must be inside a method, constructor, initializer block, or static initializer block. In this case they should probably be in a constructor or method.
