Java Stream 批量设置 MaterialDocumentDifference 对象的 postingDate 字段值

To set the field value "postingDate" as 10 in a List of MaterialDocumentDifference objects using a stream, you can use the following code: \n\nList<MaterialDocumentDifference> materialDocumentDifferences = new ArrayList<>(); \n\n// Add MaterialDocumentDifference objects to the list \n\nmaterialDocumentDifferences.stream() \n .forEach(md -> md.setPostingDate(10)); \n\nThis code uses the forEach() method of the Stream to iterate over each MaterialDocumentDifference object in the List and sets the postingDate field to 10 using the setter method setPostingDate().
